ROM Hack Decoder for *.mods files / sprites in 999

[WiiUBricker]

In 999 are the movie files in mods format. I couldnt find any information regarding that format and how to decode it.
The sprites are in the cha folder in dat format. They dont seem to be lz77 compressed because BatchLZ77 couldnt do anything with these files.
Anyone?

I haven't a clue but if you find anything out let me know. I'm a sprite ripper myself but getting the character portraits from screenshots isn't a great option for this game.

Messing around in a few tile viewers I could definitely make out some things from those dat files but nothing usable.
