Yeah I agree it is not as bad at all. I think it's a decent job, the cab looks well built.
I just wouldn't link Commodore with "arcade". Of course the C64 does have some good arcade conversions and other great games.
Did you guys know that there once were arcade cabs with Atari 8 bit homecomputers inside ? They were called Max-a-flex and were built by Exidy. They played timed games like Boulderdash and Flip and Flop ( brilliant Q*bert "follow up" by the way) This is why you can find some of these games in MAME.
