You need a bluetooth adapter(20-30 bucks at bestbuy), a Wiimote(I've heard the newest ones don't work but don't know if it's true, 40 bucks), and if you want a SNES controller then another 20 for a Classic Controller. You can do a ton of other stuff with it.
I'd start there. They have a good tutorial and compatibility guide for bluetooth adapters. If you need more help I'd be glad to help, my AIM is in my profile thingy..click my username. It's really easy to use and stuff and I love playing classics/doing random things with wiimotes!
You don't need a sensor bar xD. That's only if you want like mouse control based on exactly where your aiming. If I were to use a sensor bar, I'd use Christmas lights >D. --- Why the hell would you want to stir up more pirates vs. anti-pirate crap? Get a hobby or something, eesh. -WyrmofRust
