I'm using cfw 4.88.2 evilnat on a ps3 slim. I've tried launching the iso using managunz,mmcm, and Webmod. Everytime I launch the isos the screen goes black for a sec and then my TV says no signal, then I have to hold down the power button to turn it off. Psp games work though and so do ps3 games. I haven't tried ps1 games yet and I use component as my output if that has to do with anything.
