So I finally had a chance to set up my topgun lightguns. I didn't have as much time as I would like to test out the equilibration so keep that in mind.
I installed my lcd topgun II on a windows 7 64 bit desktop computer. It took a while to set up but here's a guide
http://maximizedemulation.wordpress.com/2010/02/15/how-to-install-topgun-ii-drivers-on-windows-7-64bit/ Honestly, setting them up was a pain in the butt. I couldn't figure out how to do it at first, but once it was figured out and installed everything was fine.
I set up the bars on the left and right of the television. Calibrating seemed to be the hardest. I followed the instructions, but it always seemed like the calibration was off when compared to where the laser was pointing and the mouse cursor on the desktop. When I pointed the gun the pointer (the mouse pointer) would follow right behind. According to this post
http://forum.arcadecontrols.com/index.php?topic=92986.0, this is normal and as soon as you pull the trigger it updates instantly. I didn't get to try this as I found this post right after testing.. the lag between the pointer and laser threw me off and made it very hard to navigate so maybe turning of the laser would help.
I also noticed that I had to be pretty far from the tv, I couldn't play while sitting on the couch so I had to move behind my couch to have some accuracy (about 7 feet away!). I do wonder though... I had the bars settup flush with the monitor, if I had them sticking out a bit and maybe tilted in.. would that help? Something to try for next time.
House of the dead 1 - Same thing, the pointer in the game would always follow behind my movements.. and it was always off by an inch. Further calibration and testing may fix this.
Mame- setting up mame was annoying at first but after I want to mame.ini and changed lightgun from 0 to 1 and within the mame front end I enabled multiple mice, it worked fine. Still, the aiming was a little off. Same experience as house for dead two and the desktop.
So keep that in mind
The drivers are beta drivers, so they may improve on them and may be different if you are using windows xp (since you can use the original driver)
Installing it and getting the gun recognized did take some work, but nothing impossible here or too technical
further calibration may make the gun have better aim
