sounds to me it is corrupted, every iso ive played works perfectly. I know one time i torrented an ISO game adn it gave me the same error.. Did you torrent it? or did u go to a rom site and get it? if u went to a rom site, did u have to download a few files then combine them? mabey something went wrong there, but if you torrented it, i would expect the iso isnt any good, usually the TRUSTED rom sites are the ones to get ur games from.. Im not sure if im allowed to link some up here so i wont, u can PM me though
also what game are u trying to play?
if its not any perticular game and just does it on every single one, mabey you just got a bad emulator file, or something.. im not sure im just throwing up ideas
