I've never worked with a criware game before, and I have no idea what I'm doing. I unpacked the cpk files, and I was planning on modding in some new skills, but I don't even have any idea what I'm looking at here, with these .emb .emm .emo .ema .bac (etc) filetypes, nor what they correlate to, what tools I should be using to view and edit them, and which ones I even need to edit for what I need to accomplish.

I've asked on the Discord server and I've asked a few people directly, but I never really got an answer.


tl;dr: 
I have no idea what the following file extensions are, and I'd like someone to explain it to me in as much or as little detail as they care to and/or link me to whatever tutorial on the subject I apparently missed:

• .emb
• .emm
• .emo
• .ema
• .bac
• .bas
• .bsa
• .ean
• .bcm
• and probably other relevant filetypes I just can't find or be asked to list.
