Nintendo DiscMan

The Nintendo DiscMan is a discontinued console that was test-released in Canada, the United Kingdom, and Australia during early 2000 and planned to have been released in the US in late 2001, for a price of £99 in the UK ($123 in the US, $167 in Canada, and $185 in Australia). The console would have been disc-based, using its own proprietary format based off of CD technology similarly to the Sega Dreamcast. The console was deemed a financial failure and discontinued some time in mid/late 2003, only having sold around 8,050 units, 9,175 games, and 925 accessories. 11 games are known to have been released for the console.

DiscModem
The Nintendo DiscMan came with a pre-packaged broadband modem peripheral, called the DiscModem. The DiscModem allowed users to select the "INTERNET" option, which allowed them to configure their internet settings. It also served as a kind of passthrough hardware for the "Internet Explorer 5.0: DiscMan Edition" game disc, which was also pre-packaged.

DiscMemory Pak
The Nintendo DiscMan also had a ram expander called the DiscMemory Pak available at retail, which sold for £9 and made certain games run smoother.

DiscMan Optical Format (DOF)
The DiscMan Optical Format is a proprietary optical format specifically made for the Nintendo DiscMan, similar to the GameCube's Minidiscs and the Wii/Wii U's optical discs. They were based off of CD technology, similar to Sega's Gigabyte Disc format for the Sega Dreamcast. A standard DOF-ROM disc can hold up to roughly 425 MB, due to their size being smaller than that a standard CD-ROM.
