Can someone recommend the best option for a USB encoder for this set up, 2 joysticks (for Robotron) 1 track ball 8 or 10 buttons. Single player. It will connected to PI3 but I don't think that is relevant. Currently using mame4all and have Robotron, Centipede, Pack-man, 1942, Asteroids all working 100% I only intend to add a few more , just my favorites.
Thanks,
Alan
