Im using a physical psp with cfw. psx2psp games i have no issues 99% of the time. one game in 20 i cant unzip right to get the eboot and folder. but with psp iso games i can not figure out the correct way to unzip to play. even though i find the boot and eboot. i have read and followed several " this is how you do it" videos and steps. but nothing works. Please help.
