Hey,

I decided to take a look at the 3DS game Yo-kai Watch today but unfortuantely after decrypting and unpacking the ROM, it appears all data except for audio and pre-rendered video is packed into one single huge archive (~344MB). File extension is .fa, but the header magic appears to be ARC0H. I uploaded two 10MB examples from the beginning and end here, please have a look: https://mega.co.nz/#!tcozzRzQ!SjM_RzXxI ... Drvm9YP3z0

I can easily find a lot of Japanese text like the game title, menu options etc in the file, so I guess there are plain text sections. Would be great to have an unpacker and repacker, if somebody feels like doing it

E: There is an unpacker on github https://github.com/polaris-/3ds-xfsatool

Cheers!

The github tool you've linked works fine to unpack the .fa files, even works fine for Youkai watch 2, after that its all .xc files containing models and textures but those are encrypted too.

Hello, can you tell me how to handle that github tool?
(I'm not good at speaking English. So I use the Google translation app for help.)
