Super Smash Bros. Ultimate Ripping Project

So when I check the models for this game on the main site, there's these textures I'm not familiar with. The ones I know are "Col", "NOR", and "PRM".
Can someone tell me how to obtain these textures or if there's a guide link me to it?

Those are textures used for the games PBR shading. They are just extracted color channels from the PRM and NOR textures turned into their own image.

I get that but how exactly are they created? I know it involves image editors like GIMP but how to actually do it is where I'm stuck.
