There's very little information online on lightgun technology. There are a few brief summaries but nothing I've found that really goes into the technical aspects of it. I understand that different systems will do things differently but I can't find an explanation of any kind anywhere that really goes in depth (or even gives a good technical summery).
I'd like to use a microcontroller to interface MAME to a real lightgun which I think is actually possible now that groovymame exists and since I'm a CRT fanatic I've of course got a nice setup to play with.
I suppose what I'm asking is, how does MAME deal with lightguns in general? Just hook into memory locations and translate mouse movements? I assume MAME in most cases doesn't go to the trouble of emulating specific lightgun controller boards as there's no real need.
I know I sound really stupid but it's hard to ask a question when you really aren't sure how to form the question.
