God Eater Burst

[jimkage]

    Does someone know how to play DLC missions on the japanese version ? I can't access most of the DLC missions they send me right back to the main menu when I try to start the mission.
You see back in the day I used to play I had to update the game with iso tool is there any way to update the game through iso tool via the ppssp emulator ? I tried but the emulator crashed. e.e
