Marvin's is probably the only old arcade left. It's still run by the same family. The original owner just passed away last year.
The big arcade on the east side was called Galaxy in Roseville. It was across the street from Macomb Mall on Gratiot Ave. It closed about 15 years ago, it's now a store called Precision Jewelers. I don't know who the owners were, but it's a place to start looking.
You could check with Big Toys Arcade, which is an arcade game retailer and repair shop in Sterling Heights. They might have some leads on information:
