Uberjack has released a new version of the Commodore 64 Emulator for PSP, heres whats new:
This is a bugfix release, fixing two issues in version 2.1.2:
Bugfix: Saving state while in NTSC mode resulted in a crash
Bugfix: An extra line from the screen border appeared while in NTSC mode
Please note that any existing NTSC save states you may have from 2.1.2 may still crash the emulator - if that happens, delete the save state.
