XP32 has a Game Controllers setup and I believe the default is the keyboard but the mouse can also be used.
The best bet is to get a PC adapter and use an XBox wireless controller. I
believe this only works with M$ games, for example, Flight Simulater. Someone correct me if wrong.
You can get the adapter and controller together for fairly cheap through Craigslist. (I sold the pack for about $30 last year.)
