Can multimann load PS1/PS2 games in .cso? Specifically speaking, if I used "PSP ISO Compress" to comress a non-PSP ISO file would it run? If so, how high should the compression rate be to avoid lag? If not, is there a PS2 or PS1 compression tool that I can use to decrease file sizes? EDIT: Using "PSP ISO Compress" didn't work. It stopped responding and created an empty .cso file. So what program, if any, would work?
