Just the .pbp file No need for folders, just put it into wherever you would've put your bin/cue files. Do rename it into something more recognizable though, Eboot.pbp isn't exactly helpful :3
Sorry, I just jumped into this thread wanting to give FF7-8-9 a try again on my psvita, whats this talk about "pbp" making games smaller, does that remove the need for big bin files?
