Today [C*] posted a guide on PSX-Scene with the help of plamenz on how to get Assassin's Creed Brotherhood working on PS3 JailBreak with PlayStation 3 Firmware 3.41.
For those already with the video game, here it is as follows: DO NOT SIGN ONTO PSN WITH THE BLES VERSION OF THIS GAME. IT ISN'T OUT UNTIL FRIDAY!
BLUS VERSION IS OUT NOW SO THAT'S FINE.
I have tested it on external with Hermes v4 with PSN, with disc inside. My Gaia manager didn't have the patch to 3.41 option, but I edited the game's .sfo anyway.
1. Install patch : EP0001-BLES00909_00-AC2TITLEUPDATE01-A0101-V0100-PE.pkg
2. Make empty folder ASSASSIN_ISO in USER DIR at BLES00909
3. Start Open Manager 2.1 +L2 patch to 3.41 ([C*] says: Or just edit the game's .sfo to 3.41)
4. Put some BD game
5. Start from BD icon
6. Wait for some mandatory install
7. Play the game and njoy
Tested 250GB Pal PL3+PSN iLLNESS. To be clear the folder has to be made in the folder of the game dump, not the update folder.
Link to the patch: (BLES00909 only)
Props to plamenz.
Update: An alternate US version (BLUS30537) guide by robg1983 is now posted HERE.
