Hows about they don't work with all games? If you used that search, you'd know that. Look, I ain't gonna start getting into why you shouldn't get them. If you're gonna mod, save for it and keep the money. If you don't want to mod, at least consider a HDD and HDLoader. But as I said, you're set on getting those Sh*teMagic 3.3 discs, so go ahead - there's no point in telling you any more... I know my mod is fine and always has been - even to this day I can get online with SOCOM with my mod enabled, and if you're chip is flashable, a fix will soon be released so hang in there - don't give in yet.
