RetroPad32 - The 32-bit ARM based joystick adapter
The RetroPad32 adapter is a joystick adapter compatible with several classic controllers from those good old beloved systems such as the Sega Genesis, Super NES, NES, Sega Saturn, and others.
It doesn't only accepts several controllers as input, but it also allows you to connect those retro-controllers to your PC, PS1, PS2, PS3, Classic XBOX, Game Cube, Nintendo 64, Nintendo Wii, Sega Dreamcast and more! Oh, do you want to play your Nintendo Switch with the Sega Saturn or Sega Genesis controllers, for example? Now you can! :)
