They did not advertise NFL and other art on thier site. That was all done via craigslist.
No, you won't find any other details about the case. I just happen to know something about what went down and it was a conversation with some at CAX who were in the know.
Yes, the FEDS were involved. The typical early morning siezure of assets at the store. All artwork confiscated. Web site had to be stripped of all copyright art. Cabinets and PCBs from china shipped separately and installed at the store. All of this went down I think in the 3rd week of July. Hit the news Aug 11.
There had been some experimenting as well with cocktail cabinet design as they sold the best. Control setups for head to head and horizontal game layouts. Bar high chair tables. I think the majority of the sales were to home users wanting the classics for the man cave. Decent construction, light weight and durable. Some games played for crap since the controls were all wrong but for the most part it gave people that no nothing of Mame an easy way to play the classics.
