Wii Startup Disc (found Wii software disc; 2006)

The Wii Startup Disc was a disc containing a system update for the Nintendo Wii console, seemingly intended to be shipped with the first released Wii units. While there exist large amounts of evidence for its existence, the physical disc has not been found, nor has a rip of it been found.

While the Wii Startup Disc was rumored to be required for the console's initial startup in pre-release rumors, and the disc was shown on the initial versions of the Wii box, it was never shipped to consumers.

According to an old blog post on a now abandoned Wii hacking blog called HackMii, a developer discovered that a very few early Nintendo Wii units shipped to customers required the disc, even though no such disc was provided. Apparently, said units that required the disc were accidentally shipped to customers, and had to be sent back to Nintendo to be fixed. As most of the very few purchased by customers were sent back, there exist very few, possibly less than a thousand, Wii units that require it.

While very, very few Wii units that required the disc were shipped to customers, a substantially higher amount were shipped to retailers to be used for kiosk demos- there are reports of sightings of the screen on store kiosks in late 2006. According to Bushing, the developer who wrote the blog post on HackMii, there are reports from retail workers seeing the physical disc, indicating that it was shipped with kiosk units.

While the Wii Startup Disc error message is not lost and has been thoroughly documented, the disc itself is lost. While it is known that the disc was just a software system update, the specific content of the disc is unknown as the disc did not ship with any systems that were purchased by consumers (as far as is known), and it is unknown if any retailers are still in possession of the disc. No concrete info, physical copy, or digital rip of the disc has surfaced, although it is likely that Nintendo is still in possession of copes of the disc.

Update:

"Excalibur0123" on Reddit claims to remember owning the disc, however neither him nor his family worked in retail and he does not remember seeing the error screen. However, this claim has not been backed up, so it is uncertain if he actually did own the disc. If he did, this would be a case of the disc being shipped to customers, possibly in a mixup of some sort.
