I'm having trouble getting this set up to work with MAME. I can shoot, but the cursor never moves when I move the gun, it just stays in the middle of the screen. The gun works great in Model 2 emulator, for PC Games (ie. Mad Dog McCree), and is fine when in Windows. I'm using MAME version 0.126u1 and the latest TopGun II drivers.
Edit: I got the gun working, I'm just having trouble now with the offscreen reload. I enabled offscreen reload in the game ini file in the mame/ini folder. Also, in the TopGun Control Panel, I set "Set offscreen to" to button 2 (B). My test game is lethal enforcers. I can get the go to reload if i quickly snap the gun down and press the trigger but it's hit or miss and sometimes takes a few attempts to get it. I'd like it just reload when I press the B button on the gun.
