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"
Your AVCHD folders must be AVCHD and not blu-ray type (i.e. INDEX.BDM and not index.bdmv).
There is a major problem with memory management. Loading so many PNGs caused 'game copy' process to stall or quit because of not sufficient memory. I'm trying to fix the issue and I'll release it.
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.
