How do I open this file?

[Resistiv]

Whoops, sorry! I probably should have included that info with the screenshot: it was arc_000106D0.MCM, specifically at the offset of 14D60. Interestingly enough, this MCM seems to have a lot of human-readable strings after the header, making me believe that this MCM may have been a texture/sprite container unlike some of the other observable MCMs.
I also remember finding an unpacked .bin file that was plain human-readable code of some sort, but I can't remember what file... (not related to that MCM though)
