This is a new build of PicoDrive, compiled from the latest sources.At the moment, it's only available for phones with 64k screen (6600, 7610, 6630, etc...).
Features:
-Game Genie support
-ROM patch support
-Soft reset
-Portrait full, displaying Genesis full resolution, with the possibility to scroll left/right in the middle of the game
-soft reset and pan left/right(to use with "Portrait full" mode) keys are configurable
-Alternate renderer, that might help sometimes, though it presents similar problems to v0.50
-Accurate timing option (may affect the speed) : try turning it on if you're experiencing problems with some game.Otherwise, let it disabled
-Accurate sprites option (may affect the speed) : try turning it on if you're experiencing problems with some game.Otherwise, let it disabled
-excellent compatibility
-region selector: if you're noticing the music is slow in some game, like Sonic the Hedgehog or Sonic the Hedgehog 2 beta, change the region (US/NTSC should work for these games)
-save state files are compressed to save space on disk


Quick Notes:
*Use your phone's default font to see the region selector in "screen options".If you use another font, it might not appear
*enabling all sound chips improves compatibility.Try it when some game crashes
*To disable sound emulation and having the games running almost full speed with no frame skipping, go to "Configure sound" and disable Z80, YM2612 and SN76496."Volume" doesn't make any change in sound emulation.It's only a volume control
*if you notice the sound lose synchrony, press "C" two times to get it working fine again
*your phone may freeze totally if you get a incoming call, switch to other application, hold menu key, or get a "battery low" warning (or any other kind of popup) while PicoDrive is running a game.ALWAYS go to main menu before switching to another application
*If after starting a game you go to main menu, switch to another application and then switch back to PicoDrive, the emulator won't allow two keys to be pressed at the same time anymore.When this happens, use a application such as AppMan, and switch to "Main" application.In some phones, you can just hold Menu and switch to "Main", though i'm not sure if it also works.
*There's a small problem with patch support that it's decreasing the address by 1.That means, if you want to write FF to the address 0x2424, you have to enter this in Picodrive:
002425:FF

ROMs:
you can get Genesis ROMs to test the emulator in the site h**p://www.romnation.net/srv/roms/genesis.html

just make sure to download ROMs marked with a [!] , since they are the good dumps.ROMs that don't have this sign in their file names aren't totally faithfull to the real cartridge.

if you experience any problem with some game (some glitch, very very very slow speed, or crashes): enable all three sound chips, turn on "accurate spites" and "accurate timing", and turn off "alt. renderer".If the game still doesn't work, enable "alt. renderer".If even so there's no success, please DO report it in this topic the game that's not working.

"Virtua Racing" doesn't work cause Sega Virtua Processor emulation isn't implemented yet.
