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!
