I have a PSP slim with cfw 5.00 m33-6, I have a little problem, I was playing ISO files and CSO file fine on my 4GB memory stick, I bought a fake 16 GB MS (not knowing) and it would only play ISO files smaller than 1GB, now I have gone back to my original 4GB stick and I can play ISO files any size but now my CSO files don't even show up on the psp even though they are in the iso folder, any one have this problem, any fixes?
Also I have format my memory stick twice, also reset my psp and my ISO mode on the vsh menu is Sony NP9660.
Problem resolved, it was a pair of bad CSO files. I guess when I put those files on to my fake 16GB, the files must have been corrupted. Sorry about that, I was worried for a while.
