MissingNo., the famous Pokémon glitch, is a bug that duplicates items and corrupts save data

the gist

MissingNo. is an unofficial Pokémon species that appears in Pokémon Red and Blue when the game's programming is pushed into an unintended state. Certain in-game events can trigger it, and the encounter produces graphical garbage. It also changes the player's inventory by increasing the count in the sixth slot by 128, which made it a popular trick. Nintendo warned that the glitch could corrupt save data. Despite being a bug, it became one of the most famous glitches in video game history and boosted the series' attention among fans.

how it works

The glitch happens when a specific sequence of in-game actions makes the game read data from memory outside its normal list of Pokémon. The game then displays whatever bytes it finds there as a species with a corrupted sprite and name. Because that memory also holds the inventory, the item count in one slot changes, which is why the glitch has that effect.

so what

MissingNo. shows how a programming error can become a cultural object, with fans trying to fit it into the games' canon and sociologists studying its impact on gaming culture. It is a reminder that many famous game moments were accidents.
