I picked up Shikigami no Shiro III for Wii, and with Murasama out and TvC on the way it looks like I need an arcade joystick for Wii.

The Wii is Gamecube compatible, but apparently the only controllers that work are GC game pads with Nintendo chips in them; none of my PS2/Xbox/GC joysticks work with Wii, nor do any of my PS2>Xbox/GC adapters work with any of my PS1/2 joysticks. My Nintendo GC controller works fine though.

My options so far are to drop $60 on that Fighting Stick Wii, but I don't want to use anything that connects to the Wii remote. Or get a Classic Controller or GC controller and hack it into another joystick (which I'd have to build, costing more money) or perhaps one of those RetroUSB SNES adapters would work? I could use the SNES Advantage or Capcom Fighter Power Stick, but it'll probably only work with an official Nintendo control pad.

Does anyone have a RetroUSB SNES adapter and a joystick to try out? Or any other ideas?
