mp3pro).\r

+ISO files can also be .cso compressed or zipped (but not mp3 files, as they\r

SonicCD_02.mp3 audio track 1 (CD track 2)\r
SonicCD_03.mp3\r
...\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 or too slow, you have encoded\r
- your MP3s incorrectly. You will have to re-encode and/or resample them.\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
* 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

This option allows to switch between 16bit and 8bit renderers. The 8bit one is\r
a bit faster for some games, but not much, because colors still need to be\r
converted to 16bit, as this is what Gizmondo requires. It also introduces\r
graphics problems for some games, so it's best to use 16bit one.\r

#ifdef PSP\r
This option allows to switch between fast and accurate renderers. The fast one\r
line by line, like the accurate one does. But because of the way it works it\r
can't render any mid-frame image changes (raster effects), so it is useful only\r
for some games.\r

Changelog\r
---------\r
+1.40\r
+ + Added support for SVP (Sega Virtua Processor) to emulate Virtua Racing,\r
+ wrote ARM recompiler and some HLE code for VR.\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).\r
+ * Fixed a bug where some key combos didn't work as expected.\r
+ * Fixed a regression in renderer (some graphic glitches in rare cases).\r
+ * Adjusted fast rernderer to work with more games, including VR.\r
+ * Fixed a problem where SegaCD RAM cart data was getting lost on reset.\r
+\r
+1.35b\r
+ * PSP: mp3 code should no longer fail on 1.5 firmware.\r
+ + PSP: added gamma adjustment option.\r
+ + Added .cso ISO format support. Useful for non-FMV games.\r
+ * It is now possile to force a region after the ROM is loaded.\r
+ * Fixed a sram bug in memhandlers (fixes Shining in the Darkness saves).\r
+ * PSP: fixed another bug in memhanlers, which crashed the emu for some games\r
+ (like NBA Jam and NHL 9x).\r
+ + PSP: added suspend/resume handling for Sega CD games.\r
+ + GP2X: added additional low volume levels for my late-night gaming sessions\r
+ (in stereo mode only).\r
+ + GP2X: added "fast forward" action in key config. Not recommended to use for\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
+ * PSP: fixed incorrect CZ80 memory map setup, which caused Z80 crashes and\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
