John, I contacted Mark about a week ago and he said they should be ready for shipping soon. I'm trying to remember from your video, did you have a custom marque made for yours? That switcher is going to be a life saver. Even though they are not hard to switch like you said in the video it will become a real pain in the ass to pull the machine out all the time.

I didn't install a custom marquee. I have the JR marquee with Dk3 board added to the cab. There are double donkey kong marquees out there.
Arcadeshop has it
