Running PS1 games on a hacked PSP Okay so I've had a hacked psp for quite a few years, i use the TN homebrew enabler and promethius iso loader, is there an emulator to download for me to be able to play PS1 games on here? I thought the ROMs would be isos and i could just load them on promethius but im apparently horribly mistaken.
