loaded a rip of Simpsons Wrestling (NTSC) onto slim w/CFW. after a few seconds of sound there is a loud screeching noise.
when loading the game, load screen appears for a few seconds and then PSP freezes. this didn't happen with the game when running on 3.52 M33-4.
this is a bug report, but i also want to note that the M33 team are geniuses and to say thanks for your dedication!
you guys really are the gods of the PSP homebrew scene right now. enjoy it!
