I ripped my Midnight Club 3 DUB UMD and it's like 1.4GB in iso format. My mem stick is only 1gb. I tried compressing to a cso but all it does is get to the startup credits and then freezes. Is there any normal way I can make the ISO smaller?
You could also use a rip-kit on it, removing some video/audio/files clearing up some space, sure you may miss stuff, but I dont think the story is what matters in MC anyways, though I could be wrong
You can also use a program called "Ciso Converter v1.00 GUI v0.65 for psp" that converts iso to cso for a smaller file.
