I know, people don't read :)
SirPoonga:
I think I could control via serial port using the RTS pin. The question is can I get mame to output to serial port. I don't know mingw too well. There might be a library to grab or something.
But then it could be adapted to USB if needed, plenty of serial to usb adaptors out there.
JoyMonkey:
How about the parallel port?
Seems to me the easiest thing to do would be use AdvMame. I mentioned this earlier but nobody commented on it. The way is monitors events (like Q*Bert falling to his death) and gives you control over the parallel port would be very handy for this project. No compiling necessary. It might be able to control the serial port too, here's the scripting doc
SirPoonga:
I was looking at advmame. From what I see qbert knock is not an event. I grabbed the advmame source code and they don't modify any of the drivers, so it wouldn;t know the qbert "event". I'll have to ask on the forum.
I don't want to do parallel port because that isn't forward thinking. Legacy ports are dying. I don't like the serial idea, but there are usb to serial convertors that are cheap. There are parallel to usb convertors, but those aren't cheap.
