If you want to play on 3.41 you need to install the official Japanese 1.02 Patch [BLJM60273_[UPDATE_01_PS3FW_03.4100]_VER_01.02.pkg], in Multiman (or with FTP) go to /dev_hdd0/game/BLJM60273/USRDIR/SEC, and replace the files there from the original English release. (AG01, AG05, AG10, AG17, AG20 and AG22...)
On 3.55 it should work without the 1.02 Patch, but I haven't tested that, so if you have trouble Install the Patch, replace the files, and Enjoy!

OK, I backed up my saves, uninstalled everything, went back to OFW 3.55, updated to kmeaw CFW, installed multiman, emulation packages, and also tried some of the duplex releases and all is working great. Thanks for the help!
Yea, definitively change to kmeaw. On kmeaw both works perfectly, QA flagged too. Beware, if you install a game like sonic 1st episode or Gow, you could see a trophy error. no panic. Just reboot your console, start a BD game with trophies, (pick one you like) then everything will be fixed. (happened with Sonic and Gow, fixed starting a trophy game)
