It is cool but... I much prefer to go an emulate the real thing: if you are using a CRT anyway (2nd sentence in TFA says it's using a CRT), you may as well make the cab compatible with the good old arcade JAMMA standard, use a Pi2JAMMA adapter, and stick a Raspberry Pi into the cab.

As a bonus you can then buy old PCBs and switch between either your Pi or a real PCB.

It's also much simpler: no need for complicated controllers and whatnots for all the heavy lifting is done by the Pi2JAMMA adapter.

It's what I have: a real arcade cab (a vintage one, from the 80s) but "modernized" in that at any time I can switch between real PCBs (I've got both real vintage PCBs and vintage bootleg PCBs: a prized possession) and my Pi+Pi2JAMMA.

I take it anything that can be run in TFA can be run on a Pi: I'm not sure if that project does something that couldn't run from a Pi with a Pi2JAMMA adapter so maybe I'm misunderstanding the (cool and good looking) project.

The marquee that's a display that can change is nice: I've seen a few arcade cabs (on arcade cabs forums) that had these and they'd switch the picture depending on the game being played.
