I have been researching this for months. However, the forum topic you noted, has been the best resource for WiiMote/GlovePie scripts. This link is a little more organized, but fewer scripts. http://www.wiili.org/index.php/GlovePIE:GlovePIE_Scripts As for the magical lightgun script, I have been very disappointed. At some point, I think MAME .122, the MAME dev's added support for multiple keyboards, where now the MAME will only work with WiiMote/GlovePie if you map the outputs to PPJoy. I have been hacking for the last few weeks and got many things to work, except a reliable joystick script using the IR sensor (which would be needed for a lightgun). I have built my own wiibar for my arcade cab as well as a Wii Cliip so that I could do testing on my laptop.
