Genesis4iPhone, a Sega Genesis (MegaDrive) and Sega CD emulator for the Apple iPhone and iPod Touch has been released to the public.

Changes:

– A port of Notaz’s continued support of PicoDrive.
– New interface/GUI similar to mame4iphone.
– Sound has been heavily improved! To enable sound, goto – Now Playing and turn up the volume slider before entering a game.
– Save state support is now working.
– Supports zipped ROMs, and they happen to load much faster than unzipped ROMs…still!
– Sega CD support is implemented though currently untested by me.
