As you know I'm rockin' 5.50 Prometheus on my PSP1K, and so far it seems to be going well enough, moreso now that JoySens has wrangled my analogue stick back under my control. But I've been meaning to ask. Will having Prometheus installed in any way affect my ability to use actual UMD games, movies, etc? I do intend to buy games every now and then, if only to preserve precious memory card space for larger new games, but I need to know. Are there any games that don't work? The rather pitiful 3 games I have now (Dissidia, Monster Hunter Freedom 2 and Harvest Moon Boy+Girl) all seem to be working, but if there's a blacklist of games that don't work it seems logical I should know about it before wasting money on games that won't work. So far the list of games I'm thinking will present issues would be - LittleBig Planet. That whole update thing, I reckon the CFW will present problems. - ModNation Racers. I heard you need some code or something to play properly, dunno if it works with CFW. What else is a potential risk? Or will Prometheus play anything from an official UMD and only create problems if I've pirated the games?
