This isn't something that needs to be done; I'm just curious...

Someone I'm following on Twitter recently posted these images of a Tekken 2 cabinet that he's seen.
The first images he posted were of some screen burn from "some Pac-Man thing". (Click to enlarge)

Also, the instructions on the bezel mention "guard impact system", which seems to be from Soul Calibur.
I instantly Googled the cabinet and noticed that it's not the original.
I now wonder what it really is.
He then posted a pic of the full cabinet. (Click to enlarge)

As I said, this isn't something I really need, so please don't let this take up too much of your time.
