I traded a Neo Geo cartridge for this today.
It's future is Mame, without a doubt. Almost everything is missing. It has the pedals, the wiring harness, a coin box and a medium resolution tube (without chassis), and that is pretty much it.
I WILL NOT be redoing it as a driving cabinet though, it is going to be a joystick cabinet, although I will be wiring up the pedals so they can have functionality.
I was hoping to squeeze my 27" monitor inside the monitor head, but there is no way it would fit, I would have to build a new one. So I will probably use a 21" computer monitor and save my D9200 for something it can actually fit inside of (so it might actually end up in my Frontline after all!!!).
I am completely up in the air about controls. Well, not completely up in the air, but I can't decide if I should do 3 player, or 2 player with trackball. And unsure about a spinner.
