alright, so now here is what I have done.
1. got my bluetooth to to list the wiimote as a device.
2. using Dolphin 3.0 (wii emulator) I have fully paired my wii mote to my computer. this is necessary as it will show up in devices without it, the wiimote will keep flashing and not stay on until paired in dolphin or another program.
3. use the program "WiiCursor" to have the wiimote emulate my mouse
4. used a sensor bar to make my movements accurate.
Now my WiiMotionPlus is point and click on the desktop and my mouse does nothing. Now when I load up MAME, several versions tried, the wiimote does nothing. I simply cannot get it to keep the mouse meulation from the desktop into MAME. i have tried several options in MAME itself, choosing lightgun as: mouse, keyboard, joystick, lightgun. none of them work.

if someone could help me out in this last final step, I would greatly appreciate it.
