I say this because I just bought an 8bitdo NES-like controller to play Vs. Super Mario Bros. with. In order to make it even work, you have to install firmware. You can't do this from a Mac computer- it isn't compatible. Same goes for the Switch controller converter that lets you play with a PS4 or Xbox One controller as well. Even if I could get it to work, I just don't like the NES controller or any controller that's trying to be like it. It's a very harsh and uncomfortable controller. Same goes with controllers that want to be like the Super Famicom- although that controller is rounder, it still doesn't have the grips designed for human hands or comfortable grips and textures like every modern controller has. And I must say- aside from "no input lag" (which a wireless recreation would remove), the SFC controller was never my favorite controller to play Umihara with- the big D-Pad made diagonals difficult and the buttons were a little too far apart. Plus the oddly positioned pause button looked cool, but made pausing awkward. That and it was too thin. The Vita had many of the same issues. Playing the game on the Vita TV with a PS4 controller (or earlier, a PS3 controller) was something I preferred.
Fun fact- when I first got Umihara Kawase Shun, I used a SFC-to-PS1 converter to play it. And when I just broke into the PS1 controllers, my performance was better. I tried to order two PS1-to-SFC converters to help with SFC games as well as extend the short cords, but never got them for whatever reason and never ordered other ones. And my experiences have been better and less expensive. Sometimes, you just have to trust console manufacturers and create new memories instead of trying to fabricate old ones.
