According to OP:
"Change the select screen params for any big portrait or name in any mode for any member simultaneously.

This is a project I've dumped.. too many hours.. into writing. I made it for myself and now that I'm done I figured I'd share with everyone, maybe someone else will find it useful.

This is a mod that uses a .def to finitely control every single big portrait and/or name entry for every member on the vs screen in every single mode. I wrote it using inheritance trees so this mod actually allows for a stupid amount of control. Like, I overengineered the crap out of this.

I included a codebank to make it very, very easy. Look for what you wanna change in the code bank, throw it in the def and keep it moving. You don't have to write anything, only add your settings.

I just wanted to vary the scales of my characters if I was doing 1v1 vs 2v2 tag, and I wanted them smaller if I was doing 3 and 4 teams, etc. and now here we are.

The control just wasn't there. Really good natively, but I needed more. So I made it. You can have it.

Enjoy
