Would it be possible to support 4 controllers?
There are some games that support it https://en.wikipedia.org/wiki/NES_Four_Score

Hi! 👋
It's certainly possible to implement. The code is set up to theoretically support other types of input (I wanted to implement Zapper support, but I never got it to be functional). Maybe it wouldn't even be super hard to implement -- documentation is available, and it's backwards compatible with 2 player games.
Right now I'm not spending much (if any) time on this project though. If I do have the time some day it'll definitely be on my list 👍 (and everyone else is also free to have a stab at it and file a PR, of course)
