Finished up my 4-player X-men conversion/restoration recently. The project spanned a condensed 3.5 weeks, working late hours into the night. But I'm really happy with the results, here's how it looks now:
====================================
Backstory:
I picked up an old TMNT cabinet that was poorly converted to Simpsons off a local auction.
It was missing the bezel, and a lot of coin door parts, but had mostly everything else.
What was surprising was at the base of the cabinet there were 2 PCB's just laying there, unconnected.
Both were The Simpsons!
One of the boards worked 100% and was sold to help fund this restoration...
...while the other PCB has some graphics issues. I decided to hang onto the faulty one and see about getting it fixed.
My decision to convert this cabinet to a dedicated 4-player X-men was a difficult one. On one hand I really enjoyed the The Simpsons game, but on the other I've always loved the X-men arcade game and I was a big comic nerd BITD, and attribute a lot of my art influences to the comic artists of that time (Jack Kirby, Jim Lee, etc...).
I see The Simpsons cabinets pop up here and there on local sales, but I rarely see X-men, and since I owned the board already I went with that.
