You sure packed a lot of stuff into that machine!
I'm a fan of the Arcade1ups and can see when they bring value. They clearly hit an emerging market at the right time. I've messed with quite a few of these, and if you want to see what happened when I bought a whole pallet of them, check this out:

My kids have a couple in their playroom:
And I heavily modified one to turn into a Gorf. Actually used a Pacman Cabinet as the base. You can see the build here:

I saw on your video you were talking about how the existing pacman control deck artwork would be messed up when you installed your controls, and I wasn't sure why that would be if you were using a vertical format. I didn't imagine you would use a street fighter layout, so that makes sense now. You can see how I did the kids cabinet, I put a pac-man sticker over the word "move" and use a button in the joystick hole. It looks like you are shifting back to a landscape version of Hyperspin?
Good luck with the build. It's looking good.
