Fate/Unlimited Codes PS2 File Formats

[SaltyBucket]

Hey, I was trying on my own to insert the official translation of the PSP version of this game into the PS2 version. The files are packed in .AFS but when I try to extract them using AFSPacker I get a lot of extensionless 1 letter files before the program gives up.

When I look through the game's executable in a hex editor, I see it point to files in the .fpk extension, using almost the exact same directory system found in the PSP version of the game, which leads me to believe that the AFS files are actually not AFS.

I can extract the PSP .fpk files just fine, but I have no idea how to access the PS2 ones.

All I need help with is how to unpack and repack .AFS files, and then how to read and write the .seq scripts.
