Castlevania: Harmony of Despair was originally a digital-only title on the PlayStation Network (PSN) for PS3. The PS3 store has since been deprecated for new purchases (though re-downloads remain possible for past buyers). As such, there is no official retail PS3 disc version —only a digital download. Regarding ROMs / ISO Files Since the game was digital-only, a standard “ROM” (typically used for cartridge-based games) or “ISO” (for disc-based games) does not exist in the conventional sense. However, you may find digital package files ( .pkg format) that were extracted from PSN.
