We’ve preserved the BIOS from the Nintendo Entertainment System “M8” kiosk! Not to be confused with it’s much more well-known counter part the M82, the M8 could only hold a total of fifteen built in games which could not be easily swapped out by the owner.

These units included the following games: Duck Hunt, Hogan’s Alley, Wild Gunman, Balloon Fight, Ice Climber, Kung Fu, Pinball, Super Mario Bros., Baseball, Golf, Tennis, Excitebike, Mach Rider, Wrecking Crew, and Popeye. Unsurprisingly, they all match the retail releases.

Amusingly, the main PCB holding all of the data is technically the largest cartridge to ever be produced for the system. It’s a 60-pin Famicom cartridge which connects to an NES via a 72-pin converter!

As for the BIOS itself, it’s very close to the M82 but much less polished, with different graphics and text. Interestingly it also uses a music track present within the FamicomBox menu.
