Picodrive by Notaz is a Genesis/MegaDrive and SegaCD emulator for GP2x.

Changes:

* Changed sync in Sega CD emulation again. Should fix games that broke after changes in 1.51a.
* Fixed default keys rebinding when they shouldn’t.
* Fixed sram being loaded from wrong game.
* Emu should no longer hang shortly after using fast-forward.
* Fixed save states sometimes no longer showing up in save state menu.
* ARM: some asm code refactoring for slight speed improvement.
