Haven’t tried any C64 emulator before on the PSP, but did today. Works great! Installed both PSPVice and C64PSP. Both worked fine excpet that PSPVice didnt paly any sound, which is strange since the latest version should support sound.

You can get a huge amount of c64 games from sites such as, C64Games.com and C64.com

And while we are on the C64 subject, if you havent seens Joakims C64 emulator in Java, check out his site!
