Today, I looked at one of the screenshots of Bubsy 3 "No More Mr. Nice Guy!" and checked at the files, that are shown in the screenshot. 

I don't know, if I chose the right files for Bubsy 3, but I think those are the ones. I looked at definitions of each file on fileinfo.com and made theories around them. Once again, it's just a theory not a fact (but definitions of each files is true).

If you don't understand, what I'm talking about, here's the page: https://bubsy.fandom.com/wiki/Bubsy_3
