it is funny you brought this up. just 2 days ago, i decided to connect my wiimote to my pc in my cabinet to try to use it as a lightgun. i got it connected and controlling the mouse by tilting the wiimote. using glovePIE. then i found a script that used the lightbar IR tracking. so i got that workign and was easily moving my mouse pointer around the screen by pointing at it. it worked pretty good, but does not work with mame. it was fine within windows and even MALA, but as soon as i launched a game, it was no longer recognized as a mouse. i thought i had hit the jackpot and could play some good mame shooting games, but it looks like we will have have to wait a little while. im sure eventually someone will figure out how to make this work in mame.
