I have problem with AC3 (czech version, not Assassins.Creed.III.PS3-DUPLEX)
I sign EBOOT (also tried earlier with tool from TrueAncestor) and game starts but freeze in menu. It seems to me, that problem is with SELFs, "ac3mp_e_ps3_f.self" and "UplayBrowser.ppu.self". I have tried to resign them with your tool but no luck. Also I noticed, that they grew in size, are two or three times big than original files. Could it have something to do with compression? thanks!
