I don't have any "wiimotes" so I can only show you what to configure. Use the Supermodel.exe -input-system=xinput -config-inputs command to configure your controllers. (possible options -input-system=xinput , -input-system=dinput , -input-system=sdl , -input-system=rawinput )
Or manually make changes to the following entries in supermodel.ini
InputAnalogGunX =
InputAnalogGunY =
InputAnalogTriggerLeft =
InputAnalogTriggerRight =
InputAnalogGunX2 =
InputAnalogGunY2 =
InputAnalogTriggerLeft2 =
InputAnalogTriggerRight2 =
You will also have to set each controller separately in the game. TEST MENU \ AIM SET
1P X 255 0
Y 255 0
2P X 255 0
Y 255 0
I don't know if it will be helpful, but this is my configuration for 2 mice
InputSystem = rawinput
InputStart1 = MOUSE1_MIDDLE_BUTTON
InputStart2 = MOUSE2_MIDDLE_BUTTON
InputAnalogGunX = MOUSE1_XAXIS
InputAnalogGunY = MOUSE1_YAXIS
InputAnalogTriggerLeft = MOUSE1_LEFT_BUTTON
InputAnalogTriggerRight = MOUSE1_RIGHT_BUTTON
InputAnalogGunX2 = MOUSE2_XAXIS
InputAnalogGunY2 = MOUSE2_YAXIS
InputAnalogTriggerLeft2 = MOUSE2_LEFT_BUTTON
InputAnalogTriggerRight2 = MOUSE2_RIGHT_BUTTON
