Edit .UPS Patches?

So this might be a stupid question, but is there a way to edit .ups patches? Just wanted to do very minor tweaks to one I really am loving playing, but I have NO idea if its even possible. Thanks!

You can edit the patched rom in FEBuilder I think…

Oh, okay. I didn’t know you could do that. I’m INCREDIBLY new to this, thank you for the super quick response!
