MEKA 0.69b - Documentation ============================ Multi machine emulator for MS-DOS, MS-Windows and GNU/Linux. (c) in 1998-2004 by Omar Cornut / Bock (omar @ cornut.fr) and contributors. Original sound engine by Hiromitsu Shioya / Hiro-shi. Implement code based on Marat Fayzullin, Maxim, Ulrich Cordes, Kittie work. Implement Emu2413 from Mitsutaka Okazaki. ========================================================================== Official website: http://www.smspower.org/meka ========================================================================== This documentation is best viewed with a fixed width font. ---------------------------------------------------------------------------- Level 0 : I am a busy guy ---------------------------------------------------------------------------- If you are looking for how to register, press Up, Down, Right, Left and start directly at Level 7. However I strongly recommend reading the whole documentation, if only to make me think I haven't wrote it for nothing. ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- Level 1 : Introduction ---------------------------------------------------------------------------- MEKA is a multi machine emulator, originally started as a Sega Master System emulator, and generally very oriented toward Z80-based Sega 8-bit systems. MEKA officially emulates the following systems: - Sega Game 1000 / SG-1000 / Japan, Oceania - Sega Computer 3000 / SC-3000 / Japan, Oceania, Europe - Super Control Station / SF-7000 / Japan, Oceania, Europe - Sega Mark III / MK3 / Japan + FM Unit Extension / MK3+FM / Japan - Sega Master System / SMS / World Wide - Sega Game Gear / GG / World Wide - ColecoVision / COLECO / America, Europe - Othello Multivision / OMV / Japan You can play other systems on it only if you are smart enough to figure how. And if you are, I doubt you will want to play Nintendo games. So forget it. MEKA was developped by the following handsome people: > Omar Cornut / Bock (Zoop) (omar @ cornut . fr) Machine emulation, tools, graphical user interface, sound, and the rest (support files, etc.). > Hiromitsu Shioya / Hiro-shi Original sound engine, Yamaha YM2413 OPL emulator. > Marat Fayzullin / RST38H Zilog Z80 CPU Core (publicly released a while ago). Implemented with modifications in MEKA. Also with contributions from: > Mitsutaka Okazaki Software Yamaha 2413 emulator (EMU2413). > Maxim Software PSG emulator. Implemented with modifications in MEKA. > Ulrich Cordes FDC765 (floppy disk controller) for SF-7000. Implemented with modifications in MEKA. > Kittie Original Memory Editor. MEKA in its original flavor, is for MS-DOS and compatible systems. MEKAW is the codename for the MS-Windows version of MEKA. MEKANIX is the codename for the GNU/Linux version of MEKA. Generally speaking, people mentionned above are not directly involved in MEKA and may or may not want to be contacted about it. That is why I did not include their e-mail addresses. Please refer to credits at the end of this document to find web sites, or feel free to contact me if you're interested in obtaining someone's e-mail address. Now let me tell you more about the cool systems that MEKA emulates: -- on the Sega side -- The SG-1000, for "Sega Game 1000", was released in Japan in July 1983. Heavily based on the MSX hardware, it is the first known Sega home console system. It was later distributed by Grandstand in New Zealand. The SC-3000, for "Sega Computer 3000", is a variation of the SG-1000 (still compatible with it) with a keyboard, and some optional peripherals such as a printer (SP-400), a tape recorder (SR-1000), or that big extension called the Super Control Station (SF-7000), providing a 3" floppy disk drive, a Centronics printer port, and more available memory. The SC-3000 was released in November 1983 in Japan, and then was sold in certain countries around the world (Oceania and Europe), usually shipped with a BASIC programming cart. Later, Sega released some updates to these systems, including, but not limited to the SC-3000h (a re-release of the SC-3000 with a hard keyboard), and the SG-1000-II (also called Mark II). The SK-1100, for "Sega Keyboard" was an upgrade to the SG-1000 and SG-1000-II to be able to use keyboard software such as the BASIC or the Music Editor. The Mark III, released in 1985, is the first Master System compatible system. It still have the necessary ports to plug the keyboard. A FM extension was made available later, providing with a better sound hardware. FM sound is supported by most games released in Japan between 1986 and 1988, Out Run being the first game featuring FM. The Mark III is backward compatible with SG-1000/SC-3000 games, although it has a darker, slighty incorrect palette (compared to an original SG-1000 or SC-3000). In 1986 came the Sega Master System, two years after Nintendo released their crappy gray box. It was sold just about everywhere, but the Japanese version had the FM extension embedded and profited from it because of better music. Other differences with the Mark III are the 3-D Glasses mini jack port and the embedded rapid fire unit, none of them being available on non-Japanese units. The Master System is also backward compatible with the older systems, with the same palette problem as the Mark III. The Master System had an interesting success in Brazil, where Tec Toy, the official distributor, released plenty of ports from Game Gear, unreleased games and sometimes even original games of their own, up to 1997. Tec Toy released a Master System 3 for the Brazilian market, although it is in fact just a renamed Master System 2. They then later released the Master System Super Compact, and a pink colored version called the Master System Girl. Both fits in hands and allows playing a few meters away from the TV, with no direct connection. Tec Toy is still around and continuing its work on Sega systems. In early December 2002, a new and surprising package was released in Brazil, called the "Master System 3 Collection". It contains about fifty games emddedded in a white colored, SMS 2 shaped console. In July 2004, Tec Toy released its latest variation of the Master System, called the "Master System Handy". This Dreamcast controller alike shaped console fits in hands (like the Super Compact models) and embed 8 games. The Sega Game Gear was released in 1991. It is basically a portable Master System with a smaller screen, a communication port (for dual player gaming) and a bigger palette (4096 colors available instead of 64). Although old SG-1000/SC-3000 video modes are still supported, their default palette was removed so most SG-1000/SC-3000 software have wrong colors on a Game Gear (software modification is possible to fix that). -- on the other side -- There was a machine called the Othello Multivision, released in Japan, which is in fact a SG-1000 with a new shape (pretty small, and embed an incomplete keyboard) and an Othello game in ROM. Eight game cartridges were specifically released for it. They are fully compatible with SG-1000. (following text by Tincho DJ) In 1982, Coleco (COnnecticut LEather COmpany) released the ColecoVision. In those years, Atari led the home video games market with Atari 2600, a 8-bit console released in 1978. Coleco wanted to release ColecoVision with Donkey Kong, the Nintendo's arcade smash hit. But it wasn't possible; Mattel (the Intellivision manufacturer) and Atari released this game first. Anyway, Coleco could release Donkey Kong four months later, acquiring KING KONG's rights from Universal Studios (Nintendo had been demanded by Universal, due to suspicious similarities between Donkey Kong and King Kong. Some months later, Nintendo won). This wasn't the last controversy in which Coleco was involved. In 1983, a cartridge adaptor was released by Coleco. This adaptor would let you use Atari 2600 cartridge on the ColecoVision. Of course, Atari demanded Coleco; but Coleco won. Later, Coleco released Adam, a computer based on Colecovision hardware. It wasn't very successful. Colecovision's time was running out, and production was stopped in 1984. ---------------------------------------------------------------------------- Level 2 : Features ---------------------------------------------------------------------------- Graphics -------- Original VDP (Video Display Processor) functionnalities were reimplemented as accurately as possible (within my given brain ressources), including some obscure features, so most games should be displaying accurately. MEKA emulates the following display modes: - TMS9918 mode 0 (Graphics) - TMS9918 mode 1 (Text) - TMS9918 mode 2 (Graphics) - TMS9918 mode 3 (Multicolor) - SMS/GG mode 4 - SMS PAL extended 224-lines mode Including proper scrolling, line-based raster effect and sprite collision, sprite flickering (optional), and some VDP variation emulation. If your computer is slower and cannot cope with MEKA (<300 Mhz), you may want to try using Massage or BrSMS. Both of those MS-DOS based emulators are faster, although not as compatible. Sound ----- MEKA emulates both sound hardware featured in the supported systems: - SN-76496 Programmable Sound Generator (PSG) by Texas Instrument - YM-2413 FM Generator (FM) by Yamaha Although technically better, the FM hardware is only supported by certain Master System games, mostly released between between 1986 and 1989. As mentionned earlier, this hardware only exists as an add-on for the Sega Mark III, or in the Japanese Sega Master System. So for most users, FM music will sound unusual. FM emulation is disabled by default, but if you are interested in hearing how an extended Mark III or a Japanese Master System would sound, you can freely enable it back in the SOUND menu of the emulator. The 4 channels of the Programmable Sound Generator are emulated in near perfection. Data gathered from various studies (including, but not limited to excellent work done by Maxim) allows perfection to go as far as generating noises using the same sequence of pseudo random numbers as a real PSG! The Yamaha YM-2413 chipset features 9 channels, 15 pre-defined instruments, and 1 user definable instrument. 3 channels can be used for percussions, and the chipset provides hardware vibrato and amplitude modulation. Two different YM-2413 emulators are provided in MEKA: - One using the OPL chipset present on some soundcards. Newer soundcard may not works well with it. It is fast, and sounds very cool. However, it does only works under DOS and Windows 95/98/ME due to technical restrictions. It might works under Windows XP under certain conditions (enabling compatibility mode) and assuming that you have a soundcard with an OPL chipset and a BLASTER environment variable set. Using software such as DOSBox or VDMSound may allow to use it. This emulator was written by Hiromitsu Shioya, specifically for MEKA. - One synthetizing emulator. It is much slower, but sounds more faithful than the OPL emulator. It works on all systems. This emulator was written by Mitsutaka Okazaki. If for some tragic reason you want or have to use the DOS version of MEKA under a Windows NT/2000/XP system, you may want to use one of the following program: - VDMSound, sound support in DOS boxes https://sourceforge.net/projects/vdmsound/ - DOSBox, a x86 emulator with DOS http://dosbox.sourceforge.net/ (MEKA was reported to work properly with it) Sound should work natively with MEKAW throught DirectX. It is important to note that although PSG/FM emulation is excellent, sound playback using the SEAL library and some incorrect timing code is a big flaw and can damage sound on some Windows configuration. This problem is being addressed. Peripherals ----------- MEKA supports/emulates the following peripherals: - Standard, two buttons joypad: [all systems] Control with keyboard or joypads. - Light Phaser: [Master System] Control the cursor with mouse, shoot with first button (by default). Gangster Town supports 2 Light Phasers, but there's currently no way to control two separates Light Phasers in the emulator (but you can assign your mouse to both of them on the same time and double fire-power). - Paddle Control (ala Steering Wheel): [Mark III / Master System] This analog paddle is supported by a few japanese games. It is possible to use a standard keyboard or digital joystick, but a mouse is HIGHLY recommended to simulate a Paddle Control. Galactic Protector supports 2 Paddle Controls on the same time. - Sports Pad: [Mark III / Master System] This heavy trackball is supported by a few sports games. Control with mouse. First and second buttons have the usual behavior. Sports games supports 2 Sports Pad, but there's currently no way to control two separates Sports Pad in the emulator (you can assign your mouse to both of them on the same time, thought). - SK-1100 Keyboard: [Sega Computer 3000] Used in all Sega Computer 3000 specific programs such as the Sega BASIC. Control with your computer keyboard. See key assignements below in this document. - 3-D Glasses: [Mark III / Master System] MEKA let you play 3-D games using three differents methods. - The first method is handled on the software side and the one you are likely to use without any particular hardware. MEKA can show either left or right eyes screens, removing the huge jerky flickering that you can see when showing both eyes screens. As a result of showing only one side, the framerate is halved by two. - A more interesting method is to use real 3-D glasses. If you tell MEKA to keep 3-D rendering as is (showing both sides), you will be able to enjoy the effect by using a video card such as the ASUS AGP-V6600, which uses the same technology. I did not try it myself so I cannot confirm, but you should be able to play 3-D games with MEKA using such video card and its dedicated 3-D glasses. - Last but not least, the greatest way of playing 3-D games is to use real Sega Master System 3-D glasses! The TECH.TXT include description and schematic of a simple adaptor to plug such glasses on your computer, through COM ports. MEKA supports SMS 3-D glasses plugged this way and will communicate with them to enable/disable each eyes in sync with emulation. - Terebi Oekaki (TV Draw) Graphic Board: [Sega Game 1000 / Sega Computer 3000 / Mark III / Master System] This is a graphic board and pen set which was available in Japan only, and directly connected to a drawing software cartridge. Control with mouse. First button simulates a pen press, and second button simulates the pen being away from the graphic board, so you can control the cursor with a joypad as well. Using dedicated adapters, it is also possible to plug and use Sega Master System controllers into your computer. Please read the TECH.TXT about it. Interface --------- MEKA includes a dedicated graphical user interface (GUI). It should not requires particular skill to use. Just use your mouse to point and click. Experienced users that are sick of using mice are also able to use keyboard shortcuts to activate certain functions. However, to give you some fun - or, due to me being a lazy bastard - they aren't all documented or functionnal. The graphical user interface is a bit slow, and a fast machine (300+ MHz) is recommended to use it in optimal conditions, without having to skip frames. Of course, the interface can be disabled (pressing Escape) and emulation speed is not affected. The current state of this thing is that I wrote the GUI code a long time ago and that it is severely outdated now. I want to make plenty of update and add new features to it, but that will be when I'll find enough time. Other things ------------ A lot of work has been done on various things, some described below: - ZIP file support: you can keep your ROM compressed in the ZIP file format to save space, MEKA does know how to handle them. - Patching system: this allows you to tell MEKA to patch a ROM on loading, without having to modify the original file, or to patch memory (RAM, etc.) at runtime. It can be used as a basic cheating functionnality. This part requires tweaking the "MEKA.PAT" file manually or using a tool. - Smart (or Stupid) Configuration File technology: MEKA will never bother you because of a corrupted configuration file, or some unknown option in it. The file itself is rewritten and recommented everytime you quit the emulator (I once thought it was a very cool feature, and now dislike it!). - Definable video modes with some nice fullscreen effects available such as TV scanline simulation or Eagle graphic destroyer - ok, Eagle is actually very nice with a few games, R-Type coming to mind. This part requires tweaking the "MEKA.BLT" file manually or using a tool. - Save states. You can load and save in-game, using F5 and F7 keys, with up to a hundred slots for storing a game state (change with F6 and F8). In addition, it is possible to load old Massage states by renaming them to the MEKA naming convention. MEKA will automatically convert them. - BIOS inclusion. You can play the snail game in MEKA, provided you know how to access to it (alright, if you forgot, try pressing UP+1+2). Originally, MEKA was supposed to use my own reprogrammed BIOS. Then I found that someone already dumped them so I stopped working on mine and included the original one instead. MEKA even includes the Japanese Master System BIOS, which you can check by setting the machine to Japanese and booting it without any game loaded. It shows a little demo with a scrolling ground and plays the Space Harrier music theme, taking advantage of both sound chipsets. - A very precise compatibility list. MEKA was heavily tested by myself. Also thanks to all people who reported bugs, and Mxs, Jossa, Tincho DJ, for their past help with Game Gear and ColecoVision lists. - A game database, with full name, proprietary checksum, product number when available, and comments in some cases. A lot of time was spent making and updating this unique database. This permit to display full game name and select specific emulation feature per game, although this database is not needed for MEKA to function properly in most cases. This database is kept updated to reflect various game versions, and is one of the basic element of a full-featured web site in the work. - Logging of sound output to WAV and VGM formats. VGM is a logging format developed by the S8-Dev community of SMS Power. For more information, and a music archive, go to http://www.smspower.org/music. - Debugging features, making MEKA useful for various programming/debugging or even cheating purposes: - Palette Viewer - Tiles Viewer - Memory Editor - Technical Information summary - Data Dumping features - And a basic debugger (run MEKA with /DEBUG parameter). - Easter eggs / secret features: edit everything, click everywhere, try all keys combinaisons... and you may get lucky several times! Or unlucky playing Mario. ---------------------------------------------------------------------------- Level 3 : "Does it work ?" ---------------------------------------------------------------------------- I tried to make MEKA as compatible I could make it. Unfortunatly, not every single game is working perfectly with it. If you want to know which, be sure to check the compatibility list provided in the COMPAT.TXT file. If you found or suspect any bug or glitch that is not mentionned in the compatibility list, please report it to me. Your help in spotting bugs is precious. ---------------------------------------------------------------------------- Level 4 : "I just checked it... Heh ! where did you got all these games ?!" ---------------------------------------------------------------------------- SMS Power! - http://www.smspower.org This is our Internet home, and new ROM images are regularly made available from here. However, it is of your responsability to find ROM images. You may want to check links or use Internet search engine. Although SMS Power current occupation is to release new ROM images, we are aiming to slowly transform into a full-featured Sega 8-bit web museum, with hundred of pages that will make you drop tears and consider building a time machine. ---------------------------------------------------------------------------- Level 5 : Usability ---------------------------------------------------------------------------- Simply execute the "MEKA.EXE" (or "MEKAW.EXE", depending on the version you are using) file, and MEKA should be up and running. Command line options -------------------- You can also run MEKA from the command line and it will take a filename as a first parameter. Additionnal parameters are also available: -HELP -? Display command line help -SETUP Start with the setup screen -EURO -US Emulate an European/US system for this session -JAP -JP -JPN Emulate a Japanese system for this session -DEBUG Enable debugging features -LOAD Load savestate on startup -LOG Log message to file (appending it) -NOELEPHANT Just what it says Keys ---- The default keyboard mapping is detailled in sections below. Common to all systems --------------------- D-Pad ...................... Arrow Keys Button 1 ................... Left Control Button 2 ................... Left Alternate Master System / SG-1000 ----------------------- Soft Pause ................. Space This is the same pause as if you pressed the button on a real machine. It can be used only if the game supports it at the moment you press it. On some game, pressing pause will get you a menu, etc.. Hard Pause ................. Alt-P or F12 This "special" pause with simply freeze the game, without changing anything. It is usable everytime, everywhere. Soft Reset ................. Backspace This is the same reset as if you pressed the button on a real machine. It can be used only if the game supports it at the moment you press it. On some emulated systems that does not support software reset, like the Game Gear, pressing this key will actually produces an hard reset. Hard Reset ................. Alt+Backspace This "special" reset with completly reset the emulated system. It is usable everytime, everywhere. Game Gear --------- Start ...................... Space Hard Reset ................. Backspace SC-3000/SF-7000 (anytime using the SK-1100, in fact) ---------------------------------------------------- Soft Reset ................. Break Other keys are mapped at the same place as the Sega Keyboard (SK-1100). So be sure to look at the provided picture carefully. For example: Control .................... Caps Lock Graph ...................... Left Control The "Pi" key, also used to type the "Ro" kana in Japanese, has unfortunately no equivalent on today's PC keyboard of many countries. Because of this, you can also either use the backslash key on the bottom left of your keyboard, OR the slash key on the keypad, to replace the missing "Pi" key. ColecoVision ------------ Numeric Pad ................ Keys 0 to 9, Minus and Equal Miscellaneous keys ------------------ Switch to next fullscreen blitter ........................ F1 Switch between automatic and standard frameskipping ...... F2 Decrease speed (automatic) or frameskip (standard) ....... F3 Increase speed (automatic) or frameskip (standard) ....... F4 Save Game State ............ F5 Load Game State ............ F7 Previous/Next Slot ......... F6/F8 Show FPS counter ........... Alt+F Change control device ...... F9 Enable/Disable keyboard .... Alt+F9 Enable/Disable sprites ..... F11 Enable/Disable background .. Alt+F11 Quit emulator .............. F10 Save screen to a file ...... PrintScreen (*) Switch fullscreen/windowed.. Alt+Enter (*) To use the PrintScreen key with MEKA/DOS under a Windows environnement, you have to tell Windows to stop intercepting the event. There is a checkbox in the properties panel. If PrintScreen doesn't work for you, please contact me. Notes ----- [DOS version] To use a mouse (for the graphical user interface, and Light Phaser / Paddle emulation), be sure to have an appropriate driver loaded in DOS mode. Some drivers or system are known to cause problems. Try another driver in this case, such as "Cute Mouse Driver", and be sure to report if you are having such problem. [All versions] I am interested in implementing analog support for certain peripherals. This is one of the obvious MEKA lack. It will be done whenever possible. How to use SC-3000 and SF-7000 Software --------------------------------------- Original SC-3000 games were the same as for SG-1000, being provided as cartridge and thus loading the ROM is the only thing you need to do to make them run. However, since the SC-3000 provided a BASIC cartridge, and more over, the SF-7000 an easy way to store programs (on floppy), homemade programs may prove being trickier to load. SF-7000 disks are rarely self-bootable (this is of course the case of the Disk Basic), and for most of them they need to be run from inside of the Disk Basic. Once it is loaded and running, load the floppy disk (.SF7 extension) you want to use, and type the FILES command to be given a list of files on the disk. To load a specified program, use LOAD "program name" where the program name is usually ending with the .BAS extension. You can move your cursor to the line the FILES listing gave you, add the LOAD command and press enter, that'll do it. Afterward, the RUN command will start the program. The cassette drive (CLOAD command on Disk Basic, and LOAD on original) is not yet emulated and thus you will not be able to use it now :-( Note that I am always looking for SC-3000 tapes, if you have some you can part, they might prove being useful in the future. I am gathering many of them currently, and of course hope to be able to work on tape emulation someday :) How to use the debugger ----------------------- To enable the debugger, set 'debug_mode' to 1 in the configuration file. Else, you can enable the debugger for a session by executing MEKA with the /DEBUG command-line parameter. In debug mode, an additionnal menu is added to the top, with access to the debugger and data dumping facilities. The debugger can also be switched on and off using the Scroll Lock hotkey. Debugger commands: (return) Step into b Step over b Break at addr c Continue without break j Jump to addr m [] Memory dump at addr d [] Disassembly at addr ?,h Help While debugging, you can use other MEKA tools (palette, tile viewer, technical information, memory editor, data dumping facilities). ---------------------------------------------------------------------------- Level 6 : "It is slooooooooow !!" ---------------------------------------------------------------------------- MEKA was mostly programmed by me, in C language, with few parts in x86 assembly. It is being hand optimized since a long time, but some things still aren't very fast. One of the reasons for that is that it emulates machines properly. To list a few things, MEKA graphic engine, palette and collision detection all support raster effects (line-per-line). Of course it includes other features that do not help making emulation faster, either. Other emulators may or not include those features or use different coding practices, so that you may want to try them if MEKA doesn't run properly for you. Of course, being worried of doing my best, I am always interested in your feedback if you have to use MEKA over another emulator. One of the biggest flaw, that is well known and unfortunately not yet fixed, is that its synchronization to target speed (eg: 60 Hz) isn't perfect and video refresh are not always optimal. It can be improved in various ways, look in the "MEKA.BLT" file for more information about it. And now, for some tricks: [DOS version] Try running MEKA in pure DOS mode (not under Windows 95/98/ME). Use VESA video modes if possible (see "MEKA.BLT"). [Windows version] Use DirectX video modes if possible (see "MEKA.BLT"). Try upgrading your DirectX drivers. [UN*X version] You are already too smart or self-complicating to need guidelines :) [All versions] Close all unused boxes in the interface. For exemple, palette and tiles viewer may slow things down, depending on the game. Disable YM-2413 FM emulation for games that supports it. The digital YM-2413 emulator slows down emulation dramatically. Or disable whole sound emulation. Or erase MEKA. ---------------------------------------------------------------------------- Level 7 : "Man, I still like MEKA !" - How to register ---------------------------------------------------------------------------- Thanks. In this case, if you want to help further development and support the author, you are welcome to register MEKA. To do so, you will simply have to help the SMS Power cause. This can be done by several ways: - The first is to donate Sega 8-bit cartridges. I would love that. Donating hardware is even more welcome. If you plan to donate anything, be sure to e-mail me beforehand. And remember it is not because a game or a system is common that I have it or I'm not interested in duplicate for whatever crazy reason. - You can send money (via PayPal or other means). Money helps SMS Power in buying cartridges to dump and/or for the museum, as well as getting weird pieces of related hardware. Due to me trusting the cool people who are happy to help a great cause, there is no more minimal amount to send to get registered. So basically even if you send $1 you will get registered. Of course the more the better: I honnestly tend to get depressed when someone send $1 for a 5+ years work. If you don't have an idea on how much you must send, then you are not on the right track. What matter is that you are helping a cause, and for that reason the more is always the better. Don't stop feeding your children or plan to sell your house to donate the money to our cause, though. Just think about how much *you* would pay for that software if it was commercial. And don't think too fast that you are such a poor guy: if you can use a computer and have access to the Internet, you are probably not. I like to have fun writing documentations, so here is a formula to calculate a good price: P = (S / (k * 5)) + (M / k) Where: P is the price a nice guy would pay (in US$ in this equation). S is the speed of your CPU. M is the amount of memory in your video card. k is defined as 5 * Pi for year 2004, and will increase with time. (5 * pi equals approximately 15.7079) And now some exemple, For my own computer (2003): P = (350 / (5 * Pi * 5)) + (8 / (5 * Pi)) = $4.95 (pretty cheap) For my own computer (2004): P = (600 / (5 * Pi * 5)) + (64 / (5 * Pi)) = $11.71 A big-fat computer: P = (3000 / (5 * Pi * 5)) + (128 / (5 * Pi)) = $46.34 (ouch) With in-between prices for average computers, obviously. Isn't that a great idea to accomodate programs prices to the speed of your computer ? The rich pay more than the poor. :) Of course if you end with something like 19.50 or 26.25 don't bother sending coins, you can round it up. And of course you can still round it up without any specific reason, it you feel it is too much or too low to pay. In fact, you are the one who decide! Better not sending checks, since they are expensive to cash (for me). Better not sending money orders, since they are expensive to send (for you). In both cases, it is not worth wasting a lot of money on a small donation. Of course, if you want to donate a million, we can find an arrangement. Cash in your country currency is usually a good thing. Please e-mail be beforehand if you are unsure about anything. My address is: Omar Cornut 45 rue Rebeval 75019 Paris France And I can also receive money with PayPal.com (very practical), under the following address: cornut @ noos.fr. Finally, if your main pretext for not registering is lazyness, then you know yourself it is not a valid pretext :) If you do not agree these terms, then you can delete this software now, as it will destroy your computer after a certain amount of time using a non registered version. Also, if you have dogs living in your house, MEKA will autodetect them and kill them by sending ultra sonic waves through the PC speakers. Just don't say I made it for the money, please. Registered users will receive information and new version before others. They will also get access to ROM on SMS Power, other things I might show off, and more importantly: a clean conscience. Enjoy! ---------------------------------------------------------------------------- Level 8 : Reasons to use MEKA instead of those other emulators ---------------------------------------------------------------------------- There is no reason why you should use it instead of another emulator. USE IT IF YOU LIKE IT. I first made MEKA for my own use, to play my own cartridges on my own computer. So competing with any other emulator is not my primary goal. Eventually, it becames a big project and aim for perfect compatibility with games, exotic peripherals and development features. I try to do quality releases, that is why MEKA is not so often updated. Testing is a tedious process. Please please report any bug or unexpected behavior you notice. Your e-mail are invaluable. I don't answer every of them (lack of time), but be sure that I do read everything. MEKA is meant to be used to play and enjoy games. Please enjoy games with it. MEKA should be kept updated, in respect for registered users. If I ever have to drop MEKA on my side, finding someone to continue the project wouldn't be hard. Or releasing the sources, maybe. Of course, since I am a maniac Sega 8-bits fan, I don't see me dropping the project anytime. ---------------------------------------------------------------------------- Level 9 : I am a freak, tell me everything ! ---------------------------------------------------------------------------- MEKA was made the open way, in the sense that many of its features are user accessible to let everyone do modifications. Here is a quick description of the ressource files that comes with MEKA: --MEKA.CFG-- or --MEKAW.CFG-- This is the configuration file where MEKA stores most of the options and user definable parameters. Some are accessible from the interface, but some, more complex ones, are only available by manually editing this file. It should be self explanatory, but here are some comments: Common sample rate values are 11025, 22050 and 44100, the highest being the best quality but also the slowest. Today's computers being fast, MEKA defaults to 44100. Screenshots and music dump filename templates are configurable for those who have websites and likely would like to avoid renaming a hundred of file, or generally if you want to share the produced files. Templates uses LibC's printf() formatting rules, which am I going to explain quickly, and for use in that context. printf() gurus will pardon me. (In an ideal world, I would write code to avoid using printf() formats, but I barely have time for more important things now.) The syntax of the string used by MEKA must be in that form: ...%[.name_max_length]s...%[0number_padding]d.file_format Where things inside brackets are optional and '...' is anything you want. When I say "anything you want", you can truly put anything you want, with two exceptions: - if you want to use spaces, replace them with asterix (*) characters. - if you want to use %, double them - or be prepared for a crash. screenshots_filename_template = %.5s_%02d.png (DOS default setting) Limit game name to 5 characters and pad capture number to 2 characters. Save file in PNG format. Playing "Psycho Fox.SMS" will get you capture filenames such as "Psych_01.png" or "Psych_42.png". %s-%02d.png (Windows & UN*X default setting) Does not limit game name, pad capture number to 2 characters. Save file in PNG format. Playing "Psycho Fox.SMS" will get you capture filenames such as "Psycho Fox-01.png" or "Psycho Fox-42.png". %s*(%d).bmp Does not limit game name, and let capture number as it is. Save file in BMP format. Playing "Psycho Fox.SMS" will get you capture filenames such as "Psycho Fox (1).bmp" or "Psycho Fox (42).bmp". Available file format for screenshots are PNG (default), BMP, PCX, TGA. Incorrect use of this feature can leads MEKA to crash in a horrible and painful way. You were warned. --MEKA.BLT-- This file contains the configuration for fullscreen video modes. It is self documented. I strongly suggest giving it a look to enable the best video modes for your system (see Level 6 of this documentation). Maxim's MEKA Configurator allows you to edit this file easily: http://www.smspower.org/maxim/mconfig/ --MEKA.INP-- This file contains inputs configuration. It is automatically rewritten by MEKA when quitting, and most of its options are available from the GUI. However, experienced users may want to tweak with it and try to use some of the top-secret options it offers. Maxim's MEKA Configurator allows you to edit this file easily: http://www.smspower.org/maxim/mconfig/ --MEKA.MSG-- This file contains text messages used in MEKA and allows you to create translation in new languages or dialect using latin characters. An extension to use asian (or other) type of characters is planned but unfortunately not to be done very soon. --MEKA.NAM-- This file contains the name, product numbers and comments database that are used by MEKA. If you are curious you can edit it. And if ever you have comments to add about any games in it, send them to me for future inclusion in the distribution version. --MEKA.PAT-- This file allows you to tell MEKA to apply simple patches to a ROM on loading, or to memory (RAM, etc.) an runtime. Nothing extraordinary but programmers and hackers will find such feature useful. Additionnally, it can be used as a basic cheating functionnality, and you can convert Pro Action Replay codes to MEKA patching system easily. The file is self documented. --MEKA.THM-- This file contains themes available from the user interface. If available GUI colors are boring you, this is the place to check. The file is also self documented. Maxim's MEKA Configurator or Lilac's Wonder Theme allows you to edit this file easily. Both tools are linked from MEKA homepage. You can also get pictures for uses with some of the default themes at: http://www.smspower.org/meka/themes --MEKA.DAT-- This file contains data used by the emulator and its interface. Editing it will shows you a bunch of garbage so it is not a really good idea. ---------------------------------------------------------------------------- Level 10 : Cool things to do when playing games is not enough ---------------------------------------------------------------------------- Connect to an Efnet IRC server and join #smspower and/or #meka to meet happy and strange people.

You will get the SALAMANDER CROSS and be able to change into Hu-Man. (Written by Clint Dyer, for Sega of America) ---------------------------------------------------------------------------- Level 13 : End Credits ---------------------------------------------------------------------------- I would like to thank the following persons: Hiromitsu Shioya (Hiro-Shi): for having done the basic work on sound/music emulation in MEKA. Without him, you may be still using the emulator with crap and buggy sound! Mitsutaka Okazaki: he wrote a software YM-2413 emulator that he available in MEKA. http://www.angel.ne.jp/~okazaki/ym2413/ Phillip Smith: for being a cool guy, having shared a lot of things together and being one of the kickstart behind SMS Power as a dump-maniac site :) Mike Gordon: another nice guy who like toying with hardware stuff. He also brought some very interesting things to the growing Sega 8-bit emulation scene. and generally has been very helpful to me. http://www.smspower.org/smsreader Maxim: for general support, various work, and being a nice guy. Maxim is the author of countless programs related to MEKA and the SMS. His work includes the first and probably always best VGM player as a plugin for WinAMP, a VGM player running on the SMS, various other VGM tools, a CHIP8 emulator also on SMS, SMS Checker, MEKA Configurator, a SMS Tile Decoder, working on a Phantasy Star retranslation project, and various demos, including embarrassing Bock's Birthday demos. He also studied the PSG chipset used on Sega 8-bit systems and his implementation is used in MEKA, although screwed up by my poor support code. http://www.smspower.org/maxim Nicolas Warren (Heliophobe): for general support, various work, and being a nice guy. Nicolas is the author of SMEG, the great SMS emulator for Dreamcast, and as made various contributions to the SMS development scenes, with homemade programs (such as the world famous Tetracycline game, and Damiana - with sources to be released soon). http://www.kenseiden.com http://www.kenseiden.com/smeg http://www.smspower.org/heliophobe Casiopea, Masato, RedS, Sankichi, Skyhigh, Toshi, Yakmo, Yoneda, Yujiro: doumo arigatou to my all Japanese friends, for being friendly, shared lots of information, brought help, support, dumps, fun, and helping to improve my collection ^_^ http://bto8.smspower.org (Casiopea) http://www.loose-logic.com (Masato) http://bto8.smspower.org/segapower (Toshi) http://village.infoweb.ne.jp/~fwik0826/ (Yoneda Mitsunori) http://www.geocities.co.jp/Playtown-Denei/8588/ (Yujiro) David Michel (Rony): for Magic Engine, support, advice, help and being my second hard drive, all back in good old days. http://www.magicengine.com Nicolas Hamel (Gouky): for the invaluable help at the very beginning. A while ago. http://www.multimania.fr/gouky James McKay: for Massage (which got me interested again in SMS!), and because when I asked him plenty of crap questions, back in the days, he kindly answered me with details. Very nice guy. http://www.enterspace.org/world/massage.htm Charles Mac Donald: for SMS Plus, sharing lot of things together - nice chats, and being one of the most productive hardware tester and hacker. Impressive person. He studied and documented obscure aspect of many SEGA console systems. http://cgfm2.emuviews.com Eric Quinn: for being there a long time ago already, dumping a few ROM, and managing an excellent SMS site (The Sega Notebook). Eric is also an active member of the S8-Dev research community, author of a promising development-oriented emulator (MesaDX), and released some early SMS code. http://shell0.elnet.com/~gm-quinn/sms/ Marc Le Douarain: for help with SF-7000 emulation and dumps of his old disks. Ulrich Cordes: for providing the base source code of the FDC-765 (floppy disk controller), as used for SF-7000 emulation. It was actually rewritten but the original technical work is from him. Gary Pierce (Youltar): for his SmsCartPad adapters, CD labels, 3-D glasses and rapid fire schematic. http://www.smspower.org/smscartpad Mr Lee, Billy Jr: for being impressive hardware hackers and doing a lot for the "scene". http://www.billyjr.com Marat Fayzullin: for Master Gear, for being one elder all emulation users and authors should respect, for having released the sources of most of his emulators and CPU cores. Also because he wrote an early technical document about the Master System. Marat is one of the father of console emulation. http://fms.komkon.org Ricardo Bittencourt: for BrSMS and BrMSX (great emulators), and various SMS software. http://www.lsi.usp.br/~ricardo/brsms.htm Martin Konrad: martin is one of those young genius who will someday take over the world, and put me to despair and shame, if I'm not working for him by then. http://emukon.kontechs.de http://www.smspower.org/martin Jon (the unknown one): this guy is the one who wrote the (old) document with all the knowledge on which the first emulators were based. I am also pretty sure the first dumps came from him. Although I doubt he's still on the internet, I would love to be in contact with him. Jon, if you're reading, e-mail me :) Super Majik Spiral Crew (the): for having written a technical documentation about the SMS. Richard Talbot Watkins: for having written a technical documentation about the SMS (although I found it after most of the early work and it didn't helped me much!).

One line reports trigger activity. The last line goes (theoretically) low when the phototransistor is lit." Dump Masters (ViperZ and Omega): for having dumped a few ROM (including some crappy Brazilian hacks ;) http://www.emucamp.com/dump_masters Charles Doty: this guy contributed a lot to the console development scene. He also wrote an old text demo for Game Gear, which is from where I started learning Z80. http://www.pcisys.net/~cdoty/console Lasse Reinikainen & Image/Helsinki/Finland: for beta testing and tons of ROM dumps, including the old and original Master System BIOS. Before getting it, me and Martin Skog spent a lot of time recreating it from stratch. Then a few days before the release, Lasse sent me the ROM. Believe it or not, there was only one different pixel between the original Sega logo and the one I drew by looking at my TV :) Dirk Stevens: for having released the sources of his Eagle graphic filter, supported in MEKA if you enable the corresponding blitter. Leonardo Pires (s0rcerer): for great support, advice and help in various things. http://emucity.unae.com Nicolas Lannier (Archeide): for SNEmul, support, advice and help. http://www.epita.fr/~lannie_n/english.html Richard Mitton (Nodrog): for TNZS-Emu, RAZE, support, advice and help. http://www.emucamp.com/tnzs Mxs: for having done the old GG compatibility list and some smart beta testing.
