See, there's tasteful Mame conversions, and there are tacky conversions.
Tasteful would include using the existing artwork/theme in conjunction with new controls. IE the Q-Bert conversion posted recently in Project Announcements.
Tacky would include hacking off the sides to put on a four player panel. Or maybe using the existing panel, but using the marble contact paper stuff as an overlay. I did exactly *one* CP like that, and scrapped it. It looks like crap.
So if this is Mame'd - and Mame'd well, I applaud. Seems this would make either a killer Multi Williams, or some hybrid thereof, since it already has a Joust bezel.
If I lived close, I'd take this in a second. Robotron is one of my must-have games.
