Homebrew dev Akop Karapetyan has released a new version of his ColecoVision emulator for PlayStation Portable, ColEm PSP.

Changelog:

• Now clearing all RAM to zeros (Heist works)
• Now padding smaller ROMs with 0xFFs in LoadROM()
• Fixed Reset9918() to reset VDP completely (Boulder Dash and Frogger)
• Implemented SCREEN2 table address masking, thanks to Daniel Bienvenu
• New save file format - not compatible with previous version

Developer's note:
Just to re-emphasize, save state format has changed, so your old save states will not be compatible with the new version. Keep both versions if you don’t want to throw away all your hard work.
