I had a sound set that I compiled using classic gaming sounds LONG LONG LONG ago.
I can look for it. I've always been meaning to post it here so customers could use it with the layouts.
You can do custom sets based around anything, some great sites exist with MK of SFII sounds.
But the one I did was classic based, some PACMAN and DK effects.
Anyway................I'll look and post if I can find it.
I also suggest people look into the Arcade Ambiance Project.... really cool.
