I am looking for and answer on setting up multiple controllers. I wish to use some USB Atari, NES, and SNES controllers (6 in total). I would like to configure all to work with the proper emulators and be able to plug in 2 controllers for the game system i wish to play. Haven’t purchased the controllers yet until i confirm this is possible. I also do not have retro pie installed but i have used it in the past. Any guidance would be appreciated.

Thanks in advance
