Ever wondered how every kid knew about Missingno and other glitches? It's because it was on the official Pokemon website.
http://web.archive.org/web/20000229111353/http://pokemon.com/games/redbluefaq.htmlI found MissingNO, Pokémon #000 and now my graphics are messed up. What can I do?
When players capture MissingNO, their game can perform strangely, and the graphics will often become scrambled. The MissingNO Pokémon is most often found if the player incorrectly performs the Fight Safari Zone Pokémon trick. To fix the scrambled graphics, try releasing the MissingNO Pokémon. If the problem persists, the only solution at this time is to re-start the game (this means erasing your current game and starting a brand new one).
What is the “Fight Safari Zone Pokémon” trick?
This trick allows you to fight and catch the Safari Zone Pokémon outside of the Safari Zone. Here's how it works:
1. First, you must have a Pokémon with the Surf Ability.
2. Enter the Safari Zone and go to the area where the Pokémon you are trying to catch is found. Stay in the section until your time runs out.
3. Go to the Seafoam Islands by Surfing south of Fuchsia City. Make sure you do not encounter any enemies on the way, or the trick will not work. This does not include the Pokémon in the water on the way there.
4. At the edge of the islands, there is a strip of the screen that is half land, and half water. Surf on this section and just keep going up and down on it. When you encounter an enemy, it will be the Pokémon from the Safari Zone section you just left. This time though, you will be able to fight them and use the other Balls on them.
Note: Using this trick in other areas may cause the Missing No Quirk. If the directions are followed, it will work.
