Control with Wiimote+Nunchuk - minimum number of buttons needed?

[ed.crofty]

What is the minimum number of keys needed to play the game? I.e. can I map a keyboard key to multiple actions because they are used in different contexts like viewing the map vs. navigating the world vs. choosing materials from the toolbox?
I am trying to set up the game to play with a Wii Remote (IR pointer for use as a mouse plus 11 buttons) and Nunchuk (analog stick plus two buttons). I have tried Touchmote but it doesn't seem to register anything from the nunchuk. I hope WiinUPro works better.

Based on gamepad mapping, the requirements are:
- 4 main buttons
- 3 DPAD buttons
- LT,RT,LB,RB
- L joy for movement
Some of these could be overlapped, based on context (like the LT,RT,LB,RB), so the 11 button mapping could be possible.
If that helps in any way, Rewired plugin is used internally, using DirectInput on Windows.

Really curious about your use case for this - are you just testing the possibility, or doing it for accessibility reasons?

Thank you very much for your reply.

I usually prefer to play games with a controller, but found it awkward to use an analog stick (i.e. relative input) to move a mouse-type (absolute) cursor. Wiimote+Nunchuk works well for several other games that similarly have movement and pointing (FPS - Metroid Prime Trilogy; RTS - Pikmin series). I already have the hardware to use Wii controllers for the Dolphin emulator, so wanted to try it out in this game.

My other Wii controller possibility would be the 'Controller Pro U' that can act as a sideways Wiimote or Wiimote + Classic Controller, though I don't know how all the buttons would be mapped in that case.

Wow, this is a great idea in general. A modernised Wiimote as a compromise between a controller and a mouse pointer? There's definitely some potential here.
