Wanted to give a quick update on my controller situation. I had gotten 3retro bit controllers with ps2 style joysticks and a long time ago I told you guys that they worked great for racing games but were messed up for smash bros. just out of curiosity I tried them again and two of them worked fine. They just needed to be broken in a bit. I tried unplugging and replugging them in just to be sure this wasn't a fluke but I think I can actually recommend them now, though still a little hesitant.
The third one looks like it's shot though - its y axis is messed up beyond help
EDIT: yeah the controllers stopped working again...that's what I get for trusting third party
