About ----- This is yet another Megadrive / Genesis emulator for PSP, but with Sega CD / Mega CD support. Although it has been originally written having ARM CPU based devices in mind, it has now been ported to PSP too, by replacing ARM specific parts with portable C code. The base code originates from Dave's (fdave, finalburn) PicoDrive 0.30 for Pocket PC. The Sega/Mega CD code is roughly based on Stephane Dallongeville's Gens. How to make it run ------------------ If you are running a custom firmware, just copy the whole PicoDrive directory to /PSP/GAME or /PSP/GAMEXXX directory in your memory stick (it shouldn't matter which one GAME* directory to use). If you are on 1.5, you will have to use KXploit tool to create the needed files and directories, and then copy them to /PSP/GAME. I assume 1.5 users know how to do this, if not, just google for KXploit. Note that this emulator may require some tweaking of configuration settings to run some games well. For Genesis/MegaDrive, if you have any problems (game does not boot, sound is glitchy, broken graphics), try to: * enable "Accurate timing" (options menu) * enable "accurate renderer" * make sure Z80 is not disabled (in "advanced options" submenu in options). Some games may need to be reset after adjusting settings. For possible Sega/Mega CD problems, see "Other important stuff" section below. How to run Sega/Mega CD games ----------------------------- To play any game, you need BIOS files. These files must be copied to the same directory as mentioned PicoDrive files. Files can be named as follows: US: us_scd1_9210.bin us_scd2_9306.bin SegaCDBIOS9303.bin EU: eu_mcd1_9210.bin eu_mcd2_9303.bin eu_mcd2_9306.bin JP: jp_mcd1_9112.bin jp_mcd1_9111.bin these files can also be zipped. The game must be dumped to ISO format, but BIN can be used too. If you want CD music, you must use ISO+mp3 files. Audio from BIN files won't be read at all. Also BIN files are usually larger, so it's better to use ISO. ISO+mp3 files can be named similarly as for other emus. Here are some examples: SonicCD.iso data track SonicCD_02.mp3 audio track 1 (CD track 2) SonicCD_03.mp3 ... Sonic the Hedgehog CD (US) - Track 01.iso Sonic the Hedgehog CD (US) - Track 02.mp3 Sonic the Hedgehog CD (US) - Track 03.mp3 ... It is very important to have the MP3s encoded at 44kHz sample rate and they must be stereo, or else they will play too fast/slow or won't play at all. Be sure NOT to use anything but classic mp3 format (don't use things like mp3pro). ISO files can also be zipped (but not mp3 files, as they are already compressed). Note that this can cause very long loading times, which may take up to several minutes. File naming is similar as with uncompressed ISOs. Example: SonicCD.zip data track SonicCD_02.mp3 audio track 1 (CD track 2) SonicCD_03.mp3 ... Other important stuff --------------------- * If your Genesis/MD game hangs or has glitches, this is most likely because "Accurate timing" option is not enabled, or fast renderer is used (try the accurate one), or Z80 is disabled in "advanced options". * Sega/Mega CD: If the game hangs after Sega logo, you may need to enable "better sync" and/or "Scale/Rot. fx" options, found in "Sega/Mega CD options" submenu, and then reset the game. Some other games may also require "CDDA audio" and "PCM audio" to be enabled to work (enabled by default). Incorrectly named/missing mp3s may also be the cause. * Sega/Mega CD: If the background music is missing, you might have named your MP3s incorrectly. Read "How to run Sega/Mega CD games" section again. * Sega/Mega CD: If the game music plays too fast or too slow, you have encoded your MP3s incorrectly. You will have to re-encode and/or resample them. PicoDrive is not a mp3 player, so all mp3s MUST be encoded at 44.1kHz stereo. Badly encoded mp3s can cause various kind of problems, like noises, incorrect playback speeds, not repeating music or even prevent game from starting. * Sega/Mega CD: If your games hangs at the BIOS screen (with planets shown), you may be using a bad BIOS dump. Try another from a different source. * Some Sega/Mega CD games don't use Z80 for anything, but they leave it active, so disabling Z80 manually (in advanced options) improves performance. * Use lower bitrate for better performance (96 or 128kbps CBRs recommended). Configuration ------------- 1. "Renderer" This option allows to switch between fast and accurate renderers. The fast one is much faster, because it draws the whole frame at a time, instead of doing it line by line, like the accurate one does. But because of the way it works it can't render any mid-frame image changes (raster effects), so it is useful only for some games. 2. "Accurate timing" This adds some more emulation precision, but slows the emulation down. Without this option some games do not boot (Red Zone for example), others have sound problems. This options has no effect for Sega/Mega CD emulation. 3. "Accurate sprites" This option improves emulation of sprite priorities, it also enables emulation of sprite collision bit. If you see one sprite being drawn incorrectly above the other (often seen in Sonic 3D Blast), you can enable this to fix the problem. This only works with the accurate renderers (see first option). 4. "Show FPS" Self-explanatory. Format is XX/YY, where XX is the number of rendered frames and YY is the number of emulated frames per second. 5. "Frameskip" How many frames to skip rendering before displaying another. "Auto" is recommended. 6. "Enable sound" Does what it says. You must enable at least YM2612 or SN76496 (in advanced options, see below) for this to make sense (already done by default). 7. "Sound Quality" Sound sample rate, affects sound quality and emulation performance. 22050Hz setting is the recommended one. 8. "6 button pad" If you enable this, games will think that 6 button gamepad is connected. If you go and reconfigure your keys, you will be able to bind X,Y,Z and mode actions. 9. "Region" This option lets you force the game to think it is running on machine from the specified region, or just to set autodetection order. Also affects Sega/Mega CD. 10. "Use SRAM/BRAM savestates" This will automatically read/write SRAM (or BRAM for Sega/Mega CD) savestates for games which are using them. SRAM is saved whenever you enter the menu or exit the emulator. 11. "Confirm savestate" Allows to enable confirmation on savestate saving (to prevent savestate overwrites), on loading (to prevent destroying current game progress), and on both or none, when using shortcut buttons (not menu) for saving/loading. 12. "Save slot" This is a slot number to use for savestates. This can also be configured to be changed with a button (see "key configuration"). 13. "CPU/bus clock" This allows to change CPU and bus clocks for PSP. 333MHz is recommended. 14. "[Display options]" Enters Display options menu (see below). 15. "[Sega/Mega CD options]" Enters Sega/Mega CD options menu (see below). 16. "[advanced options]" Enters advanced options menu (see below). 17. "Save cfg as default" If you save your config here it will be loaded on next ROM load, but only if there is no game specific config saved (which will be loaded in that case). You can press left/right to switch to a different config profile. 18. "Save cfg for current game only" Whenever you load current ROM again these settings will be loaded Advanced configuration ---------------------- Enter [advanced options] in config menu to see these options. 1. "Emulate Z80" Enables emulation of Z80 chip, which was mostly used to drive the other sound chips. Some games do complex sync with it, so you must enable it even if you don't use sound to be able to play them. 2. "Emulate YM2612 (FM)" This enables emulation of six-channel FM sound synthesizer chip, which was used to produce sound effects and music. 3. "Emulate SN76496 (PSG)" This enables emulation of additional sound chip for additional effects. Note: if you change sound settings AFTER loading a ROM, you may need to reset game to get sound. This is because most games initialize sound chips on startup, and this data is lost when sound chips are being enabled/disabled. 4. "gzip savestates" This will always apply gzip compression on your savestates, allowing you to save some space and load/save time. 5. "Don't save last used ROM" This will disable writing last used ROM to config on exit (what might cause SD card corruption according to DaveC). Sega/Mega CD options -------------------- 1,2,3. "USA/EUR/JAP BIOS" These options just show if your BIOS files were correctly detected by the emulator (it shows the filename it is using). If so, you can press Start to test your BIOS. 4. "CD LEDs" The Sega/Mega CD unit had two blinking LEDs (red and green) on it. This option will display them on top-left corner of the screen. 5. "CDDA audio (using mp3s)" This option enables CD audio playback. 6. "PCM audio" This enables 8 channel PCM sound source. It is required for some games to run, because they monitor state of this audio chip. 7. "ReadAhead buffer" 8. "Save RAM cart" Here you can enable 64K RAM cart. Format it in BIOS if you do. 9. "Scale/Rot. fx" The Sega/Mega CD had scaling/rotation chip, which allows effects similar to "Mode 7" effects in SNES. Unfortunately emulating it is slow, and very few games used it, so it's better to disable this option, unless game really needs it. 10. "Better sync" This option is similar to "Perfect synchro" in Gens. Some games require it to run, for example most (all?) Wolfteam games, and some other ones. Don't use it for games which don't need it, it will just slow them down. Display options --------------- 1. "Scale factor" This allows to resize the displayed image by using the PSP's hardware. The number is used to multiply width and height of the game image to get the size of image to be displayed. If you just want to make it fullscreen, just use "Set to fullscreen" setting below. 2. "Hor. scale (for low res. games)" This one works similarly as the previous setting, but can be used to apply additional scaling horizontally, and is used for games which use lower (256 pixel wide) Gen/MD resolution. 3. "Hor. scale (for hi res. games)" Same as above, only for higher (320 pixel wide) resolution using games. 4. "Bilinear filtering" If this is enabled, PSP hardware will apply bilinear filtering on the resulting image, making it smoother, but blurry. 5. "Wait for vsync" Wait for the screen to finish updating before switching to next frame, to avoid tearing. There are 3 options: * never: don't wait for vsync. * sometimes: wait only if emulator is running fast enough. * always: always wait (causes emulation slowdown). 6. "Set to unscaled centered" Adjust the resizing options to set game image to it's original size. 7. "Set to fullscreen" Adjust the resizing options to make the game image fullscreen. Key configuration ----------------- Select "Configure controls" from the main menu. Then select "Player 1" and you will see two columns. The left column lists names of Genesis/MD controller buttons, and the right PSP ones, which are assigned to them. If you bind 2 different PSP buttons to the same action, you will get a combo (which means that you will have to press both buttons for that action to happen. Cheat support ------------- To use GG/patch codes, you must type them into your favorite text editor, one per line. Comments may follow code after a whitespace. Only GameGenie and Genecyst patch formats are supported. Examples: Genecyst patch (this example is for Sonic): 00334A:0005 Start with five lives 012D24:0001 Keep invincibility until end of stage 009C76:5478 each ring worth 2 009C76:5678 each ring worth 3 ... Game Genie patch (for Sonic 2): ACLA-ATD4 Hidden palace instead of death egg in level select ... Both GG and patch codes can be mixed in one file. When the file is ready, name it just like your ROM file, but with additional .pat extension, making sure that case matches. Examples: ROM: Sonic.zip PATCH FILE: Sonic.zip.pat ROM: Sonic 2.bin PATCH FILE: Sonic 2.bin.pat Put the file into your ROMs directory. Then load the .pat file as you would a ROM. Then Cheat Menu Option should appear in main menu. What is emulated? ----------------- Genesis/MegaDrive: main 68k @ 7.6MHz: yes, FAME/C core z80 @ 3.6MHz: yes, CZ80 core VDP: yes, except some quirks not used by games YM2612 FM: yes, optimized MAME core SN76489 PSG: yes, MAME core Sega/Mega CD: another 68k @ 12.5MHz: yes, FAME/C too gfx scaling/rotation chip (custom ASIC): yes PCM sound source: yes CD-ROM controller: yes (mostly) bram (internal backup RAM): yes Problems / limitations ---------------------- * 32x and SVP are not emulated. * Various VDP quirks (window bug, scroll size 2, etc.) are not emulated, as very few games use this (if any at all). * Some games don't work or have glitches because of inaccurate timing and sync between the emulated chips.

Snatcher and probably some more games now boot. * 2M word RAM -> VDP transfers fixed, no more corruption in Ecco and some other games. 1.10 + GP2X: Added experimental Sega CD support. + GP2X: Added partial gmv movie playback support. 0.964 * GP2X: Fixed a sound buffer underflow issue on lower sample rate modes, which was happening for NTSC games and causing sound clicks. * GP2X: Redone key config to better support USB joysticks (now multiple joysticks should be useable and configurable). + GP2X: Added save confirmation option. + GP2X: Added 940 CPU crash detection. + ALL: UIQ3 port added. 0.963 * GP2X: Gamma-reset-on-entering-menu bug fixed. * GP2X: Recompiled PicoDrive with gcc profiling option set as described here: http://www.gp32x.com/board/index.php?showtopic=28490 0.962 * GP2X: Fixed an issue with incorrect sounds in some games when dualcore operation was enabled (for example punch sound in SOR). * GP2X: Limited max volume to 90, because higher values often cause distortions. * GP2X: Fixed a bug with lower res scaling. * GP2X: Gamma is now reset on exit. 0.96 * ALL: Severely optimized MAME's YM2612 core, part of it is now rewritten in asm. + GP2X: The YM2612's code now can be run in GP2X's ARM940T CPU, what causes large performance increase. * ALL: Accurate renderers are slightly faster now. + GP2X: Using quadruple buffering instead of doublebuffer now, also updated framelimitter, this should eliminate some scrolling and tearing problems. * GP2X: Fixed some flickering issues of 8bit accurate renderer. + GP2X: craigix's RAM timings now can be enabled in the menu (see advanced options). + GP2X: Added ability to save config for specific games only. + GP2X: Gamma control added (using GP2X's hardware capabilities for this). * GP2X: Volume keys are now configurable. + GP2X: GnoStiC added USB joystick support, I made it possible to use it for player 2 control (currently untested). * GP2X: squidgehack is now applied through kernel module (cleaner way). 0.95 * ALL: Fixed a bug in sprite renderer which was causing slowdowns for some games. + GP2X: Added command line support + GP2X: Added optional hardware scaling for lower-res games like Shining Force. * ALL: Sound chips are now sampled 2 times per frame. This fixed some games which had missing sounds (Vectorman 2 1st level, Thunder Force 3 water level, etc.). + ALL: Added another accurate 8-bit renderer which is slightly faster and made it default. 0.945 + GP2X: Added frame limiter for frameskipped modes. * GP2X: Increased brightness a bit (unused pixel bits now also contain data). * GP2X: Suidgehack was not applied correctly (was applied before allocating some high memory and had no effect). 0.94 + Added GP2X port. * Improved interrupt timing, Mazin Saga and Burning Force now works. * Rewritten renderer code to better suit GP2X, should be faster on other ports too. + Added support for banking used by 12-in-1 and 4-in-1 ROMs (thanks Haze). + Added some protection device faking, used by some unlicensed games like Super Bubble Bobble, King of Fighters, Elf Wor, ... (thanks to Haze again) + Added primitive Virtua Racing SVP faking, so menus can be seen now. 0.93 * Fixed a problem with P900/P910 key configuration in FC mode. * Improved shadow/hilight mode emulation. Still not perfect, but should be enough for most games. + Save state slots added. + Region selector added. 0.92 VDP changes: * VDP emulation is now more accurate (fixes flickering in Chase HQ II, Super Hang-On and some other problems in other games). * HV counter emulation is now much more accurate. Fixes the Asterix games, line in Road Rash 3, etc. * Minor sprite and layer scroll masking bugs fixed. + Added partial interlace mode renderer (Sonic 2 vs mode) * Fixed a crash in both renderers when certain size window layers were used. + Added emulation of shadow/hilight operator sprites. Other shadow/hilight effects are still unemulated. + Sprite emulation is more accurate, sprite limit is emulated. + Added "accurate sprites" option, which always draws sprites in correct order and emulates sprite collision bit, but is significantly slower. Emulation changes: * Improved interrupt handling, added deferred interrupt emulation (Lemmings, etc). + Added serial EEPROM SRAM support (Wonder Boy in Monster World, Megaman - The Wily Wars and many EA sports games like NBA Jam). + Implemented ROM banking for Super Street Fighter II - The New Challengers * Updated to the latest version of DrZ80 core, integrated memory handlers in it for better performance. A noticeable performance increase, but save states may not work from the previous version (you can only use them with sound disabled in that case). + SRAM word read handler was using incorrect byte order, fixed. Changes in Cyclone 0.0086: + Added missing CHK opcode handler (used by SeaQuest DSV). + Added missing TAS opcode handler (Gargoyles,Bubba N Stix,...). As in real genesis, memory write-back phase is ignored (but can be enabled in config.h if needed). + Added missing NBCD and TRAPV opcode handlers. + Added missing addressing mode for CMP/EOR. + Added some minor optimizations. - Removed 216 handlers for 2927 opcodes which were generated for invalid addressing modes. + Fixed flags for ASL, NEG, NEGX, DIVU, ADDX, SUBX, ROXR. + Bugs fixed in MOVEP, LINK, ADDQ, DIVS handlers. * Undocumented flags for CHK, ABCD, SBCD and NBCD are now emulated the same way as in Musashi. + Added Uninitialized Interrupt emulation. + Altered timing for about half of opcodes to match Musashi's. 0.80 * Nearly all VDP code was rewritten in ARM asm. Gives ~10-25% performance increase (depends on game). * Optimized 32-column renderer not to render tiles offscreen, games which use 32-column display (like Shining Force) run ~50% faster. + Added new "Alternative renderer", which gives another ~30-45% performance increase (in addition to mentioned above), but works only with some games, because it is missing some features (it uses tile-based renderering instead of default line-based and disables H-ints). + Added "fit2" display mode for all FC gamers. It always uses 208x146 for P800 and 208x208 for all other phones. + Added volume control for Motorolas (experimental). VDP changes: + Added support for vertical window (used by Vapor Trail, Mercs, GRIND Stormer and others). + Added sprite masking (hiding), adds some speed. + Added preliminary H counter emulation. Comix Zone and Sonic 3D Blast special stage are now playable. + Added column based vertical scrolling (Gunstar Heroes battleship level, Sonic and Knuckles lava boss, etc). Emulation changes: + Re-added and improved Z80 faking when Z80 is disabled. Many games now can be played without enabling Z80 (Lost Vikings, Syndicate, etc), but some still need it (International Superstar Soccer Deluxe). * Improved ym2612 timers, Outrun music plays at correct speed, voices in Earthworm Jim play better, more games play sound. * I/O registers now remember their values (needed for Pirates! Gold) + Added support for 6 button pad. Changes in Cyclone 0.0083wip: + Added missing CHK opcode (used by SeaQuest DSV). + Added missing TAS opcode (Gargoyles). As in real genesis, write-back phase is ignored (but is enabled for other systems). Backported stuff from Snes9x: * Fixed Pxxx jog up/down which were not working in game. + Added an option to gzip save states to save space. + The emulator now pauses whenever it is loosing focus, so it will now pause when alarm/ponecall/battery low/... windows come up. - Removed 'pause on phonecall' feature, as it is no longer needed. + Video fix for asian A1000s. 0.70 * Started using tools from "Symbian GCC Improvement Project", which give considerable speed increase (~4fps in "center 90" mode). * Rewrote some drawing routines in ARM assembly (gives ~6 more fps in "center 90" mode). * Minor improvement to 0 and 180 "fit" modes. Now they look slightly better and are faster. * Minor stability improvements (emulator is less likely to crash). + Added some background for OSD text for better readability. + Added Pal/NTSC detection. This is needed for proper sound speed. + Implemented Reesy's DrZ80 Z80 emu. Made some changes to it with hope to make it faster. + Implemented ym2612 emu from the MAME project. Runs well but sometimes sounds a bit weird. Could be a little faster, so made some changes too. + Implemented SN76489 emu from the MAME project. + Added two separate sound output methods (mediaserver and cmaudiofb) with autodetection (needs testing). * Fixed VDP DMA fill emulation (as described in Charles MacDonald's docs), fixes Contra and some other games. 0.301 Launcher: * Launcher now starts emulation process from current directory, not from hardcoded paths. * Improved 'pause on call' feature, should hopefully work with Motorola phones. 0.30 Initial release.
