#ifdef PSP\r
This is yet another Megadrive / Genesis emulator for PSP, but with\r
Sega CD / Mega CD support. Although it has been originally written having\r
ARM CPU based devices in mind, it has now been ported to PSP too, by\r
replacing ARM specific parts with portable C code.\r
The base code originates from Dave's (fdave, finalburn) PicoDrive 0.30 for\r
Pocket PC. The Sega/Mega CD code is roughly based on Stephane Dallongeville's\r
Gens.\r
#else\r
This is yet another Megadrive / Genesis / Sega CD / Mega CD emulator, which\r
was written having ARM-based handheld devices in mind (such as PDAs,\r
smartphones and handheld consoles like GP2X and Gizmondo of course).\r
The critical parts (renderer, 68K and Z80 cpu interpreters) and some other\r
random code is written in ARM asm, other code is C. The base code originates\r
from Dave's (fdave, finalburn) PicoDrive 0.30 for Pocket PC. The Sega/Mega CD\r
code is roughly based on Stephane Dallongeville's Gens.\r
#endif\r
\r
PicoDrive is the first emulator ever to properly emulate Virtua Racing and\r
it's SVP chip.\r
\r
\r
How to make it run\r
------------------\r
\r
#ifdef GP2X\r
Extract all files to some directory on your SD and run PicoDrive.gpe from your\r
GP2X/Wiz menu. The same .gpe supports GP2X F100/F200 and Wiz, there is no need\r
to use separate versions.\r
Then load a ROM and enjoy! ROMs can be in .smd or .bin format and can be zipped.\r
Sega/Mega CD images can be in ISO/CSO+MP3/WAV or CUE+BIN formats (read below\r
for more details).\r
#endif\r
#ifdef GIZ\r
First make sure you have homebrew-enabled Service Pack installed. Then copy\r
PicoDrive.exe and KGSDK.dll to any place in your filesystem (both files must\r
be in the same directory) and run PicoDrive.exe using the launcher of your choice\r
(some of them might require renaming PicoDrive.exe to Autorun.exe, placing it in\r
the root of SD, etc). Then load a ROM and enjoy! ROMs can be placed anywhere, can\r
be in .smd or .bin format and can be zipped (one ROM per zip).\r
#endif\r
#ifdef PSP\r
If you are running a custom firmware, just copy the whole PicoDrive directory to\r
/PSP/GAME or /PSP/GAMEXXX directory in your memory stick (it shouldn't matter\r
which one GAME* directory to use).\r
\r
If you are on 1.5, there is a separate KXploited version for it.\r
#endif\r
#ifdef UIQ\r
Copy SIS and some ROMs to any directory in your memory stick, and install the SIS.\r
Then load a ROM and enjoy! ROMs can be in .smd or .bin format and can be zipped.\r
#endif\r
#ifndef UIQ\r
\r
This emulator has lots of options with various tweaks (for improved speed mostly),\r
but it should have best compatibility in it's default config. If suddently you\r
start getting glitches or change something and forget what, use "Restore defaults"\r
option.\r
#endif\r
\r
\r
How to run Sega/Mega CD games\r
-----------------------------\r
\r
To play any game, you need BIOS files. These files must be copied to\r
#ifdef UIQ\r
D:\other\PicoDrive\ directory.\r
#else\r
the same directory as PicoDrive files.\r
#endif\r
Files can be named as follows:\r
\r
US: us_scd1_9210.bin us_scd2_9306.bin SegaCDBIOS9303.bin\r
EU: eu_mcd1_9210.bin eu_mcd2_9303.bin eu_mcd2_9306.bin\r
JP: jp_mcd1_9112.bin jp_mcd1_9111.bin\r
these files can also be zipped.\r
\r
The game must be dumped to ISO/CSO+MP3/WAV or CUE+BIN format. When using\r
CUE/BIN, you must load .cue file from the menu, or else the emu will not find\r
audio tracks.\r
CUE/BIN usually takes a lot of space, so it can be converted to cue/cso/mp3 by\r
using bin_to_cso_mp3 tool, which is included with the emulator. See readme in\r
the bin_to_cso_mp3/ directory for details.\r
\r
ISO+mp3 files can be named similarly as for other emus.\r
Here are some examples:\r
\r
SonicCD.iso             data track\r
SonicCD_02.mp3          audio track 1 (CD track 2)\r
SonicCD_03.mp3\r
...\r
\r
Sonic the Hedgehog CD (US) - Track 01.iso\r
Sonic the Hedgehog CD (US) - Track 02.mp3\r
Sonic the Hedgehog CD (US) - Track 03.mp3\r
...\r
\r
In case there is a .cue file with properly specified files names in it,\r
file naming doesn't matter. Just be sure to load .cue from the menu.\r
\r
It is very important to have the MP3s encoded at 44kHz sample rate and they\r
must be stereo, or else they will play too fast/slow or won't play at all.\r
Be sure NOT to use anything but classic mp3 format (don't use things like\r
mp3pro).\r
\r
ISO files can also be .cso compressed or zipped (but not mp3 files, as they\r
are already compressed). CSO will cause slightly longer loading times, and\r
is not very good for FMV games. Zipping ISOs is not recommended, as it will\r
cause very long (several minute) loading times, and make some games\r
unplayable. File naming is similar as with uncompressed ISOs.\r
Example:\r
\r
SonicCD.cso             data track\r
SonicCD_02.mp3          audio track 1 (CD track 2)\r
SonicCD_03.mp3\r
...\r
\r
\r
Other important stuff\r
---------------------\r
\r
* Sega/Mega CD: If the game hangs after Sega logo, you may need to enable\r
  "better sync" and/or "Scale/Rot. fx" options, found in "Sega/Mega CD options"\r
  submenu, and then reset the game. Some other games may also require\r
  "CDDA audio" and "PCM audio" to be enabled to work (enabled by default).\r
  Incorrectly named/missing mp3s may also be the cause.\r
* Sega/Mega CD: If the background music is missing, you might have named your\r
  MP3s incorrectly. Read "How to run Sega/Mega CD games" section again.\r
* Sega/Mega CD: If the game music plays too fast/too slow/out of sync, you have\r
  encoded your MP3s incorrectly. You will have to re-encode and/or resample them.\r
  PicoDrive is not a mp3 player, so all mp3s MUST be encoded at 44.1kHz stereo.\r
  Badly encoded mp3s can cause various kind of problems, like noises, incorrect\r
  playback speeds, not repeating music or even prevent game from starting.\r
  Some games (like Snatcher) may hang in certain scenes because of this.\r
  Some mp3 rippers/encoders remove silence and beginning/end of audio tracks,\r
  what causes audio desyncs and/or mentioned problems.\r
  If you have cue/bin rip, you can use the bin_to_cso_mp3 tool (included with\r
  the emulator) to make a proper iso/mp3 rip.\r
* Sega/Mega CD: If your games hangs at the BIOS screen (with planets shown),\r
  you may be using a bad BIOS dump. Try another from a different source.\r
* Some Sega/Mega CD games don't use Z80 for anything, but they leave it active,\r
  so disabling Z80 manually (in advanced options) improves performance.\r
* Use lower bitrate for better performance (96 or 128kbps CBRs recommended).\r
#ifdef GP2X\r
* GP2X F100/F200: When you use both GP2X CPUs, keep in mind that you can't\r
  overclock as high as when using ARM920 only. For example my GP2X when run\r
  singlecore can reach 280MHz, but with both cores it's about 250MHz. When\r
  overclocked too much, it may start hanging and producing random noise, or\r
  causing ARM940 crashes ("940 crashed" message displayed).\r
* GP2X F100/F200: Due to internal implementation mp3s must not be larger that\r
  12MB (12582912 bytes). Larger mp3s will not be fully loaded.\r

    problem for some games.\r
  * ARM: fixed a crash when CD savestate is loaded just after loading ROM.\r
\r
1.51\r
  * Improved bin_to_cso_mp3 tool, it should no longer complain about\r
    missing lame.exe even if it's in working dir.\r
  * Fixed a regression from 1.50, which caused slowdowns in Final Fight.\r
  * Fixed some regressions from 1.50 related to sprite limit and palette\r

  * Some other minor adjustments.\r
\r
1.50\r
  + Added some basic support for Sega Pico, a MegaDrive-based toy.\r
  + Added proper support for cue/bin images, including cdda playback.\r
    .cue sheets with iso/cso/mp3/wav files listed in them are now\r
    supported too (but 44kHz restriction still applies).\r
  + Added bin_to_cso_mp3 tool, based on Exophase's bin_to_iso_ogg.\r
    The tool can convert .cue/.bin Sega CD images to .cso/.mp3.\r
  * Greatly improved Sega CD load times.\r
  * Changed how scheduling between 68k and z80 is handled. Improves\r
    performance for some games. Credits to Lordus for the idea.\r

  * Improved renderer performance for shadow/hilight mode.\r
  * Added a hack for YM2612 frequency overflow issue (bleep noises\r
    in Shaq Fu, Spider-Man - The Animated Series (intro music), etc.)\r
    Credits to Nemesis @ spritesmind forum. Works only if sound rate\r
    is set to 44kHz.\r
  + Implemented some sprite rendering improvements, as suggested by\r
    Exophase. Games with lots of sprites now perform better.\r
  + Added better idle loop detection, based on Lordus' idea again.\r
  - "accurate timing" option removed, as disabling it no longer\r
    improves performance.\r
  - "accurate sprites" was removed too, the new sprite code can\r
    properly handle sprite priorities in all cases.\r
  * Timers adjusted again.\r
  * Improved .smd detection code.\r
  * ARM: fixed a bug in DrZ80 core, which could cause problems in\r
    some rare cases.\r

    wrote ARM recompiler and some HLE code for VR. Credits to Exophase and\r
    Rokas for various ideas.\r
  * Changed config file format, files are now human-readable. Game specific\r
    configs are now held in single file (but old game config files are still\r
    read when new one is missing).\r
  * Fixed a bug where some key combos didn't work as expected.\r
  * Fixed a regression in renderer (ARM ports only, some graphic glitches in\r
    rare cases).\r
  * Adjusted fast renderer to work with more games, including VR.\r
  * Fixed a problem where SegaCD RAM cart data was getting lost on reset.\r
  * GP2X: Greatly reduced SegaCD FMV game slowdowns by disabling read-ahead\r
    in the Linux kernel and C library (thanks to Rokas and Exophase for ideas\r
    again). Be sure to keep "ReadAhead buffer" OFF to avoid slowdowns.\r
  + PicoDrive now comes with a game config file for some games which need\r
    special settings, so they should now work out-of-the-box. More games will\r
    be added with later updates.\r
  + GP2X: Files now can be deleted by pressing A+SELECT in the file browser.\r
\r
1.35b\r

    Sega CD, may case problems there.\r
  * Some other small tweaks I forgot about.\r
\r
1.35a\r
  * PSP: fixed a bug which prevented to load any ROMs after testing the BIOS.\r

    graphics corruption in EU Mega CD model1 BIOS menus.\r
  + PSP: added additional "set to 4:3 scaled" display option for convenience.\r
  + PSP: Added an option to disable frame limitter (works only with non-auto frameskip).\r
\r
1.35\r
  + PSP port added. Lots of new code for it. Integrated modified FAME/C, CZ80 cores.\r
  + Some minor generic optimizations.\r
  * Patched some code which was crashing under PSP, but was working in GP2X/Giz\r
    (although it should have crashed there too).\r
  * Readme updated.\r
\r
1.34\r
  + Gizmondo port added.\r
  + Some new optimizations in memory handlers, and for shadow/hilight mode.\r

  * File browser now filters out mp3s, saves and some other files, which are not ROMS.\r
\r
1.30\r
  + ISO files now can be zipped. Note that this causes VERY long loading times.\r
  + Added data pre-buffering support, this allows to reduce frequency of short pauses\r
    in FMV games (caused by SD access), but makes those pauses longer.\r
  * Fixed PCM DMA transfers (intro FMV in Popful Mail).\r
  + Properly implemented "decode" data transformation (Jaguar XJ220).\r
  * Integrated "better sync" code into cyclone code, what made this mode much faster.\r

\r
1.20\r
  * Fixed a long-standing problem in audio mixing code which caused slight distortions\r
    at lower sample rates.\r
  * Changed the way 920 and 940 communicates (again), should be more reliable and give\r
    slight performance increase.\r
  * Some optimizations in audio mixing code.\r
  * Some menu changes (background added, smaller font in ROM browser, savestate loader\r
    now can select slots).\r
  + 1M mode DMA transfers implemented (used by FMV games like Night Trap and Sewer Shark).\r

0.962\r
  * GP2X: Fixed an issue with incorrect sounds in some games when dualcore operation\r
          was enabled (for example punch sound in SOR).\r
  * GP2X: Limited max volume to 90, because higher values often cause distortions.\r
  * GP2X: Fixed a bug with lower res scaling.\r
  * GP2X: Gamma is now reset on exit.\r
\r
0.96\r
  * ALL:  Severely optimized MAME's YM2612 core, part of it is now rewritten in asm.\r

          performance increase.\r
  * ALL:  Accurate renderers are slightly faster now.\r
  + GP2X: Using quadruple buffering instead of doublebuffer now, also updated\r
          framelimitter, this should eliminate some scrolling and tearing problems.\r

          high memory and had no effect).\r
\r
0.94\r
  + Added GP2X port.\r
  * Improved interrupt timing, Mazin Saga and Burning Force now works.\r
  * Rewritten renderer code to better suit GP2X, should be faster on other\r
    ports too.\r
  + Added support for banking used by 12-in-1 and 4-in-1 ROMs (thanks Haze).\r
  + Added some protection device faking, used by some unlicensed games like\r
    Super Bubble Bobble, King of Fighters, Elf Wor, ... (thanks to Haze again)\r
  + Added primitive Virtua Racing SVP faking, so menus can be seen now.\r
\r
0.93\r
  * Fixed a problem with P900/P910 key configuration in FC mode.\r
  * Improved shadow/hilight mode emulation. Still not perfect, but should be\r
    enough for most games.\r
  + Save state slots added.\r
  + Region selector added.\r
\r
0.92\r
  VDP changes:\r
  * VDP emulation is now more accurate (fixes flickering in Chase HQ II,\r
    Super Hang-On and some other problems in other games).\r
  * HV counter emulation is now much more accurate. Fixes the Asterix games,\r
    line in Road Rash 3, etc.\r
  * Minor sprite and layer scroll masking bugs fixed.\r
  + Added partial interlace mode renderer (Sonic 2 vs mode)\r
  * Fixed a crash in both renderers when certain size window layers were used.\r
  + Added emulation of shadow/hilight operator sprites. Other shadow/hilight\r
    effects are still unemulated.\r
  + Sprite emulation is more accurate, sprite limit is emulated.\r
  + Added "accurate sprites" option, which always draws sprites in correct\r
    order and emulates sprite collision bit, but is significantly slower.\r
\r
  Emulation changes:\r
  * Improved interrupt handling, added deferred interrupt emulation\r
    (Lemmings, etc).\r
  + Added serial EEPROM SRAM support (Wonder Boy in Monster World,\r
    Megaman - The Wily Wars and many EA sports games like NBA Jam).\r
  + Implemented ROM banking for Super Street Fighter II - The New Challengers\r
  * Updated to the latest version of DrZ80 core, integrated memory handlers\r
    in it for better performance. A noticeable performance increase, but save\r
	states may not work from the previous version (you can only use them with\r
	sound disabled in that case).\r
  + SRAM word read handler was using incorrect byte order, fixed.\r
\r
  Changes in Cyclone 0.0086:\r
  + Added missing CHK opcode handler (used by SeaQuest DSV).\r
  + Added missing TAS opcode handler (Gargoyles,Bubba N Stix,...). As in real genesis,\r
    memory write-back phase is ignored (but can be enabled in config.h if needed).\r
  + Added missing NBCD and TRAPV opcode handlers.\r
  + Added missing addressing mode for CMP/EOR.\r
  + Added some minor optimizations.\r
  - Removed 216 handlers for 2927 opcodes which were generated for invalid addressing modes.\r
  + Fixed flags for ASL, NEG, NEGX, DIVU, ADDX, SUBX, ROXR.\r
  + Bugs fixed in MOVEP, LINK, ADDQ, DIVS handlers.\r
  * Undocumented flags for CHK, ABCD, SBCD and NBCD are now emulated the same way as in Musashi.\r
  + Added Uninitialized Interrupt emulation.\r
  + Altered timing for about half of opcodes to match Musashi's.\r
\r
0.80\r
  * Nearly all VDP code was rewritten in ARM asm. Gives ~10-25% performance\r
    increase (depends on game).\r
  * Optimized 32-column renderer not to render tiles offscreen, games which\r
    use 32-column display (like Shining Force) run ~50% faster.\r
  + Added new "Alternative renderer", which gives another ~30-45% performance\r
    increase (in addition to mentioned above), but works only with some games,\r
    because it is missing some features (it uses tile-based rendering\r
    instead of default line-based and disables H-ints).\r
  + Added "fit2" display mode for all FC gamers. It always uses 208x146 for\r
    P800 and 208x208 for all other phones.\r
  + Added volume control for Motorolas (experimental).\r
\r
  VDP changes:\r
  + Added support for vertical window (used by Vapor Trail, Mercs, GRIND\r
    Stormer and others).\r
  + Added sprite masking (hiding), adds some speed.\r
  + Added preliminary H counter emulation. Comix Zone and Sonic 3D Blast\r
    special stage are now playable.\r
  + Added column based vertical scrolling (Gunstar Heroes battleship level,\r
    Sonic and Knuckles lava boss, etc).\r
\r
  Emulation changes:\r
  + Re-added and improved Z80 faking when Z80 is disabled. Many games now can\r
    be played without enabling Z80 (Lost Vikings, Syndicate, etc), but some\r
    still need it (International Superstar Soccer Deluxe).\r
  * Improved ym2612 timers, Outrun music plays at correct speed, voices in\r
    Earthworm Jim play better, more games play sound.\r
  * I/O registers now remember their values (needed for Pirates! Gold)\r
  + Added support for 6 button pad.\r
\r
  Changes in Cyclone 0.0083wip:\r
  + Added missing CHK opcode (used by SeaQuest DSV).\r
  + Added missing TAS opcode (Gargoyles). As in real genesis, write-back phase\r
    is ignored (but is enabled for other systems).\r
\r
  Backported stuff from Snes9x:\r
  * Fixed Pxxx jog up/down which were not working in game.\r
  + Added an option to gzip save states to save space.\r
  + The emulator now pauses whenever it is loosing focus, so it will now pause\r
    when alarm/ponecall/battery low/... windows come up.\r
  - Removed 'pause on phonecall' feature, as it is no longer needed.\r
  + Video fix for asian A1000s.\r
\r
0.70\r
  * Started using tools from "Symbian GCC Improvement Project", which give\r
    considerable speed increase (~4fps in "center 90" mode).\r
  * Rewrote some drawing routines in ARM assembly (gives ~6 more fps in\r
    "center 90" mode).\r
  * Minor improvement to 0 and 180 "fit" modes. Now they look slightly better\r
    and are faster.\r
  * Minor stability improvements (emulator is less likely to crash).\r
  + Added some background for OSD text for better readability.\r
  + Added Pal/NTSC detection. This is needed for proper sound speed.\r
  + Implemented Reesy's DrZ80 Z80 emu. Made some changes to it with hope to make\r
    it faster.\r
  + Implemented ym2612 emu from the MAME project. Runs well but sometimes sounds\r
    a bit weird. Could be a little faster, so made some changes too.\r
  + Implemented SN76489 emu from the MAME project.\r
  + Added two separate sound output methods (mediaserver and cmaudiofb) with\r
    autodetection (needs testing).\r
  * Fixed VDP DMA fill emulation (as described in Charles MacDonald's docs),\r
    fixes Contra and some other games.\r
\r
0.301\r
  Launcher:\r
  * Launcher now starts emulation process from current directory,\r
    not from hardcoded paths.\r
  * Improved 'pause on call' feature, should hopefully work with Motorola phones.\r
\r
0.30\r
