I'm VERY new to PS3 CFW. Sorry if this is in the wrong place. 1. I see many different tutorials regarding PS2 on PS3 as far as PS3 CFW goes, and many of them appear to be outdated. That said, do I NEED reactPSN, and if yes, what exactly do I do with it? Also, do I just put in a PS2 Disc to install the game as an ISO? 2. I don't plan to sign-in to PSN on the PS3 now that it's on CFW, but I'd like to keep it connected to the internet. What steps should I take to prevent updates? 3. I see all this talk about placing PS3 Games on dev/hdd and the like. How exactly am I supposed to do that?
