RFE: Provide a mapping to use wiimote as joystick device

[J. Félix Ontañón]

Wiimote emulating joystick device should be a default mapping to play games because the wiimote it's a joystick.

A good joystick mapping for this should contain:
- Wiimote arrow pad as axis
- Wiimote A,B as main buttons
- Wiimote Home as start button

And probably the use of Nunchuck:
- Nunchuk stick as main joystick axis
- Nunchuk C,Z as secondary buttons

I think this could be a good mapping. I've tested it successfully with sdlmame.
I attach a .wii mapping package file for wiican 0.3 series.

# Gamepad axis 0 (analog)
Nunchuk.Stick.X = ABS_X
Nunchuk.Stick.Y = ABS_Y

# Gamepad axis 1 (absolute)
Wiimote.Dpad.X = ABS_HAT0X
Wiimote.Dpad.Y = ABS_HAT1X

# Main gamepad buttons
Wiimote.A = BTN_A
Wiimote.B = BTN_B
Nunchuk.C = BTN_C
Nunchuk.Z = BTN_X

# Other gamepad buttons
Wiimote.Home = BTN_START
Wiimote.Minus = BTN_SELECT
Wiimote.Plus = BTN_MODE
Wiimote.1 = BTN_Y
Wiimote.2 = BTN_Z

The game pad mode seems to work well. What about a Light Gun mode? Can the IR Sensor be set to be an axis without affecting mouse movement?

[J. Félix Ontañón (fontanon)]

I suppose this could work:

Plugin.ir_ptr.X = ABS_HAT0X
Plugin.ir_ptr.Y = ABS_HAT0Y

Could you test? I'm waiting for the sensor bar, so i'll do the tests then.

[Zombie Ryushu (zombie-ryushu)]

I did, it doesn't work. I also tried

Plugin.ir_ptr.X = ABS_X
Plugin.ir_ptr.Y = ABS_Y

That failed as well.

For the joystick thing the classic gamepad mapping has been commited.
