@Japo:
NICE! Next time I visit my Dad, I'll give those blueprints to him and we can try building it.
UPDATE: The machine will now only be a UMK3 machine, and I'm gonna use an old-and-abandoned-but-good computer to run it. I have controllers I can use for the machine.
Now, what do you think of artwork:
Marquee
Side Art
Control Panel
Because I'm using gamepads for the machine, I only need this picture for where the control panel's supposed to be.
