The Famicombox is interesting. The article has a minor error - the unit houses up to 15 games, not 16. There is an internal cartridge slot for the menu ROM, but it's not a game.

All the gory details you could ever want: http://kevtris.org/mappers/famicombox/index1.html

> On X, Orochi said they went undercover to investigate the love hotel and found the Famicombox installed in every single room except for one.

I wonder if they really had info on the hotel beforehand and went to investigate or if it was a happy accident
