I pretty much want to to be able to play spinner based games but also spinner based driving games on MAME but I don't have a cabinet. I hook up my PC to my living room TV and play most games with my Xbox PC controller. I also have an X-Arcade trackball controller for trackball and lightgun games (and as a cartoonishly large PC mouse). I can built a small box for a spinner OR install a USB spinner on my X-Arcade trackball box but neither will provide me with separate analog controls for acceleration and braking in driving games. Do they make small analog buttons or levers that can take care of acceleration and braking or do I have to actually look at getting some pedals and hooking them up with something like an Optipac?
