-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

+The emulator is heavily optimized for ARM, features assembly cores for\r

+SSP16 (for 32X and SVP emulation). It was started by Dave (aka fdave,\r

Here are some examples:\r
Other important stuff\r
---------------------\r
\r
-* If your Genesis/MD game has graphical glitches, this is most likely because\r
- "accurate renderer" is not enabled (see options).\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
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
-#ifdef GP2X\r
-* When you use both GP2X CPUs, keep in mind that you can't overclock as high as\r
- when using ARM920 only. For example my GP2X when run singlecore can reach\r
- 280MHz, but with both cores it's about 250MHz. When overclocked too much,\r
- it may start hanging and producing random noise, or causing ARM940 crashes\r
- ("940 crashed" message displayed).\r
-#endif\r
* Use lower bitrate for better performance (96 or 128kbps CBRs recommended).\r
#ifdef GP2X\r
-* Due to internal implementation mp3s must not be larger that 12MB\r
- (12582912 bytes). Larger mp3s will not be fully loaded.\r
-* RAM timings option is good for dualcore operation (it is disabled by\r

- options).\r

-@@3. "Set to unscaled centered"\r
-Adjust the resizing options to set game image to it's original size.\r
+@@4. "Disable sprite limit"\r
+The MegaDrive/Genesis had a limit on how many sprites (usually smaller moving\r
+objects) can be displayed on single line. This option allows to disable that\r
+limit. Note that some games used this to hide unwanted things, so it is not\r
+always good to enable this option.\r
\r
-@@3. "Set to fullscreen"\r
-Adjust the resizing options to make the game image fullscreen.\r
+@@4. "Emulate Z80"\r
+Enables emulation of Z80 chip, which was mostly used to drive the other sound chips.\r
+Some games do complex sync with it, so you must enable it even if you don't use\r
+sound to be able to play them.\r
+\r
+@@4. "Emulate YM2612 (FM)"\r
+This enables emulation of six-channel FM sound synthesizer chip, which was used to\r
+produce sound effects and music.\r
+\r
+@@4. "Emulate SN76496 (PSG)"\r
+This enables emulation of PSG (programmable sound generation) sound chip for\r
+additional effects.\r
+\r
+Note: if you change sound settings AFTER loading a ROM, you may need to reset\r
+game to get sound. This is because most games initialize sound chips on\r
+startup, and this data is lost when sound chips are being enabled/disabled.\r
+\r
+@@4. "gzip savestates"\r
+This will always apply gzip compression on your savestates, allowing you to\r
+save some space and load/save time.\r
\r
+@@4. "Don't save last used ROM"\r
+This will disable writing last used ROM to config on exit (what might cause SD\r
+card corruption according to DaveC).\r
+\r
+@@4. "Disable idle loop patching"\r
+Idle loop patching is used to improve performance, but may cause compatibility\r
+problems in some rare cases. Try disabling this if your game has problems.\r
+\r
+@@4. "Disable frame limiter"\r
+This allows games to run faster then 50/60fps, useful for benchmarking.\r
\r
+#ifdef GP2X\r
+@@4. "Use ARM940 core for sound"\r
+F100/F200: This option causes PicoDrive to use ARM940T core (GP2X's second CPU)\r
+for sound (i.e. to generate YM2612 samples) to improve performance noticeably.\r
+It also decodes MP3s in Sega/Mega CD mode.\r
+\r
+@@4. "RAM overclock"\r
+This overclocks the GP2X RAM chips for improved performance, but may cause\r
+instability. Keep it enabled if it doesn't cause problems.\r
+\r
+@@4. "MMU hack"\r
+Makes framebuffer bufferable for improved performance. There are no drawbacks\r
+so it should be left enabled.\r
+\r
+@@4. "SVP dynarec"\r
+This enables dynamic recompilation for SVP chip emulated for Virtua Racing game,\r
+what improves it's emulation performance greatly.\r

Key configuration\r
-----------------\r
\r
Select "Configure controls" from the main menu. Then select "Player 1" and you will\r
see two columns. The left column lists names of Genesis/MD controller buttons, and\r

-the right GP2X ones, which are assigned to them. If you bind 2 different GP2X buttons\r
+the right column your handheld ones, which are assigned.\r

Changelog\r
---------\r
-1.50a\r
+1.80\r
+ + Added Caanoo support. Now the GP2X binary supports GP2X F100/F200, Wiz\r
+ and Caanoo. Lots of internal refactoring to support this.\r
+ + Enabled 32X and SMS code. It's still unfinished but better release something\r
+ now than wait even more (it has been in development for more then a year now\r
+ due to various other projects or simply lack of time).\r
+ + Pandora: added hardware scaler support, including ability to resize the\r
+ layer and control filtering.\r
+ + GP2X: Added basic line-doubling vertical scaling option.\r
+ * Changed the way keys are bound, no need to unbind old one any more.\r
+ * Handle MP3s with ID3 tags better (some MP3s with ID3 did not play).\r
+ * Improved shadow/hilight color levels.\r
+ * Fixed broken cheat support.\r
+\r
+1.80beta2\r
+ * Pandora: updated documentation.\r
+\r
+1.80beta1\r
+ + Added pandora port.\r
+ * Internal refactoring for 32x/SMS support.\r
+ * Move mapper database to external file.\r
+ + Added preliminary SMS emulation.\r
+ + Added emulation of 32x peripherals including VDP. More work is needed here.\r
+ + ARM: Added new SH2 recompiler for 32x. Some unification with SVP one.\r
+ - Disabled most of the above bacause I'm not yet happy with the results.\r
+\r
+1.56\r
+ * Changed sync in Sega CD emulation again. Should fix games that\r
+ broke after changes in 1.51a.\r

+ * Fixed save states sometimes no longer showing up in save state menu.\r
+ * ARM: some asm code refactoring for slight speed improvement.\r
+\r
+1.55\r
+ + Added Wiz support. Now the same GP2X binary supports F100/F200 and Wiz.\r
+ * Changed shadow/hilight handling a bit, fixes some effects in Pirates! Gold.\r
+ * Complete input code rewrite. This fixes some limitations like not allowing\r
+ to control both players using single input device. It also allows to use\r
+ more devices (like keyboards) on Linux based devices.\r
+ * Options menu has been reordered, "restore defaults" option added.\r
+\r
+1.51b\r
+ * Fixed a crash when uncompressed savestate is 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

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
handling (caused graphical glitches in some games).\r

* Some other minor adjustments.\r
\r
1.50\r
+ Added A r k's usbjoy fix.\r
+ Added "perfect vsync" option, which adjusts GP2X LCD refresh rate and syncs\r
emulation to it to eliminate tearing and ensure smoothest scrolling possible.\r
- + Added an option to use A_SN's camma curve for gamma correction (improves dark\r
+ + Added an option to use A_SN's gamma curve for gamma correction (improves dark\r
and bright color display for mk2s).\r
* Sometimes stray sounds were played after loading a savestate. Fixed.\r
* Fixed a problem where >6MB mp3s were corrupted in memory (sound glitches in\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 renderering\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
