Good luck with those Act Labs guns......I had two of them in my house for a week and got them to work with one game (Crossbow)....They arrived on a monday, were sent back to Act Labs the next monday....they suck and feel like cheap little cap guns.
I've been using one in my cab for a couple years with no problems at all.
All the mame games play great, but this was with .98 and earlier. I've got the older "space ray-gun" style and I've heard they don't feel
quite as cheap as the newer models.
I'm hoping I just neglected someting stupid like the input (general) config. I guess I'll find out when I get home.
