    Hiya, gbatempers.
    I'm trying to extract the contents of the Rom File System from the 3DS version of Inazuma Eleven 3 - Team Ogre Attacks. I have managed to unpack the rom, and these are the files I got:

    It seems that everything aside from the audio files is inside archive_op.fa
    Unfortunately, this archive is encrypted, and its internal structure appears troublesome. Does anyone here know how I can decrypt this file? I have tried using 3ds-xfsatool, which seems to work for other Level-5 games, but it hasn't worked. The program just crashes.

    These are the first few lines of the file viewed in a hex editor:

    Thank you in advance! [​IMG]

    Well, apart that you are in the wrong forum (it's the NDS forum and not the 3DS), I believe there are already tools for IE3.

    Whoops, sorry, my bad. I'm gonna post in the right section. Anyway, there seem to be no tools to extract the archive...
