How do you get missingno?

Answer 1

How to do the Missingno. trick(Red and Blue only) 1. Go to Viridian City.

2. Talk to the man who "has a 100 rare candy."

3. Say yes, then watch him catch a Pokémon.

4. Fly or teleport to Cinnabar Island.

5. Start Surfing on the right coast, but stay only on the part where land meets water. Going to the left won't hurt, just surf again, but going to the right will make you have to repeat the process.

You will meet high-level Pokémon, Missingno. and 'M.

Warning! If you meet a level 0 'M, do not catch it. The game will freeze when you try to withdraw it.

(you can also use action replay)(Also you can jest throw your ds/dsi/ds lite in the toilet and you might see a brown missingno)
