Supersonic Warriors 2 .arc Files - File Gurus Help Me Please

Hey, was hoping someone could help me with these files that seem to be compressed. I'm still a pretty hardcore newby at this stuff, so I would really appreciate if someone took the time to figure it out.

Contains two character files from DBZ Supersonic Warriors 2 on the DS. I know "charadata.arc" has all the various palettes inside it, and potentially other helpful things, so I decided to include it.

Thanks!
