Question

how do you make a USB coin door
for a mame Arcade Cabinet

Answer 1

If your using an interface to connect controles to your computer (ipac) then you only need to run your coin door switch to it and map it in mame as being key 5 and/or 6.
If you have done hacking of a controller for your controles then you could get another controler and hack it also and wire the coin mec sw to it.

Good Luck
