Got a few PS2 Game ISOs on the comp. Wondering how I can confirm (Without making coasters) if they are in fact the actual game - not some altered or completely different game..? Im thinking the ISO size is a start - but is there a site/post where I can confirm the correct size? Also using UltraISO to check contents. The ISOs appear to have a PS2 based file system. Anyone got any other ideas?.. Any help would be awesome.
