Have you thought about giving your manager a name, "AVCHD / GAME / FILE manager (mod of OBM by dean)" is a bit long and if you add another function it will just get longer. As you are the author of multiAVCHD a suggested name is "multiPS3 Manager"
I have a doubt in regards of Patch Mode(R2). When I'm in Game List if I press R2 it shows Insert Blu-Ray game disc... while if I have one disc inside it shows the game I have inside only in the list. Is it right? I'm sorry if I'm being too noob but it's because I have no games that need "Patched Mode" right now and for the other Managers I've used the Patched Mode didn't change/asked for a thing while on Games List.
