Reminds me of the time Namco went after one single company for selling MAME cabs with roms and namco IP artwork.
IIRC the company was located not far from themselves, so I guess it was convenient enough to pursue.d

I looked it up and the company is still in business. The artwork now just says "Multicade"
"This machine is plug and play compatible with a 3149 game board. The title of any board is the number of games included. .... The 3149 has almost every arcade game ever made!"
(was going to link the website, but I guess it might violate the rulez)
The description of the cab contains a link to an ebay auction for the "game board".
The cab itself is actually a nice looking Dynamo knockoff.
