Sorry to hijack the thread, but since we're on the subject of light gun hacking...
Is there any reason why a light gun couldn't be made to work with a DOS cabinet using a serial interface (like an Opti-Pac)?
The reason I ask is because my cabinet is DOS-based and I like it the way it is, but would like to use light guns and run Area 51 and other games. Heck, even Duck Hunt would be more fun with a light gun.
I read the page which detailed hacking a light gun for use with a PCB, and it seemed to be a simple 4-wire connection. What does the AL light gun "converter" do to switch the input(s) of their gun to something that a PC understands? Is it converting it to mouse x,y coordinates and (I'm assuming) button presses?
Bottom line, it'd be great to be able to use light guns on a DOS cabinet, but if I absolutely have to, I suppose I can always upgrade to ArcadeVGA and run Windows to get USB support. I happen to like the setup I have with AdvanceMenu and AdvanceMAME, though.
Thanks for any ideas or help.
