I'm trying to get GroovyMAME running with the new Retro Shoter 3 guns, but only one gun is being recognised. I've tried various things including enabling settings for dual lightgun, multiple mice, etc. Also tried changing the input from raw, dinput, Win32, but still with no luck.
The driver seems to be fine. A different build of MAME is also fine and allows inputs for guns 1 and 2, but I would love to have the authentic resolution with my CRT monitor. Anybody have any ideas? Thanks.
