Ah, that explains it...
The early Mr.Do! cabinets were all sold as conversion kits instead of cabinets, themselves, so that's why they were always on the mini's, and the wall and front board decal stickers were just applied over the older ones to make it look like a new game.
So, I have no idea of the story behind this full-size monstrosity... I'm just glad I got the photo!
@JulieSqveakaroo ....its creator was later a cofounder of Atlus who did work on the Megami Tensei game series
it's weird seeing these early super-popular video games and then seeing the same person also was involved in much more recent super-popular video games
