Notaz has updated his port of PicoDrive for the PSP. It’s a Genesis and Sega CD emulator.

Changes:

fixed a bug which prevented to load any ROMs after testing the BIOS.
fixed incorrect CZ80 memory map setup, which caused Z80 crashes and graphics corruption in EU Mega CD model1 BIOS menus.
added additional “set to 4:3 scaled” display option for convenience.
added an option to disable frame limitter (works only with non-auto frameskip).
