Yes ... there is a patch for 3.55 incoming and reported working... just wait a couple of days and it will appear and straight to the sticky thread I presume!
EBOOT.BIN, game.self, PARAM.SFO have been signed for FW 3.40, but i'm not sure if it compatible with FW 3.xx. I've tested it only on Rebug 4.21.1 anybody on 3.xx, test it.
Still don't know where i can test if DLC from Duplex works or not. I didn't find where i can change skins of character. Can anyone tell, where?
Actual gameplay observed with 3.41 dongle on ext w/bd-mirror- other settings may work also. Could someone plz post this fix to a better source (a couple of links were dead), thanks in advance!
