ok so I've tested this fw out and it works. The only problems I see with it are when you are in multiman or when you are playing a game you can't hit the ps button to quit game it will just keep spinning but never load icons. You have to hold the ps button then select quit game. Other than that no problems. Played mw3 online, max payne 3 online and also played resident evil 6 off external hard drive online. Games update when connected then allow for online play.
For anyone waiting and wanting to stay on 3.55 good luck with that. This cfw will play games unmodified even darksiders 2 with external mirror option. All the games i have that are already eboot fixed still work too so yeah I don't see any point in waiting unless you are waiting for an updated version that exits games properly. I just hit the eject button. Works fine. Well Hope that helps answer some questions. I was on rogero online pup and flashed ofw 3.55 thru recovery before updating to this new cfw.
