-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
-Better speed and compatibility: Now you can play more games that didn't work before, like Super Street Fighter 2 and International Superstar Soccer Deluxe.
-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 now compressed to save space on disk
Quick Notes:
*Nokia N70 users must use default theme to avoid that PicoDrive closes when you try to load a ROM.It applies to all phones whose owners are experiencing the same problem
*Use your phone's default font to see the region selector in "screen options".If you use another font, it won't appear
*enabling all sound chips improves compatibility.Try it when some game crashes
*if you notice the sound lose synchrony, press "C" two times to get it working fine again
*your mobile 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
