Psychotech - I am not sure what you mean by "how did you do the control panel front?" If you asking whats it covered or painted in, I used the stinky vinyl you get from partexpress.com, if you asking what do the buttons do, the one on left is "esc" then "player 1" "Credit" "player 2" and on the right is "pause" its interfaced with an IPAC so I use "player 1 + esc" for enter and another shifted command that escapes me at the moment. I tried to keep it as simple as possible. Loaded my compile of Mame that saves high scores on most games and gets rid of the "ok" and any other messages, kinda like that. Mamewah is the front end and I have Arcade Jukebox 8, Mame and Daphne setup. If I didnt answer your question please feel free to ask again.
Leapinlew - That professional touch was totally due to your suggestion, I have 3 more of those switches I can implement in future projects now, even easier since I know how to wire them up now!
