Persona 2 -Eternal Punishment

I am trying to get all of the PSP Persona games for my Vita, but I can not find Eternal Punishment. I actually do have an Eternal Punishment folder with a Vimm's lair text file, but it has a bin and cue file, which I don't trust that to work as much as an ISO. Had it been on here before and was removed? if so why?
