Requirements

  1. A Pokemon that evolves by evolution stone, such as Clefairy, Staryu, Pikachu, etc, as the first Pokemon in your party.
  2. One of the following Pokemon, each one of which corresponds to an evolution stone, in your party.
    •Exeggutor - Moon Stone 
    •HEX 20 Missingno. (no other Missingno will work) - Fire Stone 
    •Psyduck - Leaf Stone 
    •Growlithe - Thunderstone
    •Onix - Water Stone

Directions

1. Get into a trainer battle.

2. Have the first Pokemon in your party, the one your trying to evolve, gain a level.

3. Switch out the Pokemon your trying to evolve and put the Pokemon that corresponds to the necessary evolution stone.

4. Have that Pokemon finish the battle.

5. When the Battle is over then your Pokemon will evolve!


Additional Information

This glitch can also be done when encountering a wild Pokemon. Have the Pokemon your trying to evolve start the battle and then change Pokemon and place the Pokemon that corresponds to the required evolution stone in battle. Have the Pokemon end the battle. Both Pokemon will gain experience and for the glitch to work, the Pokemon your trying to evolve will need to gain a level from the experience it gains.

Why It Works

The reason this glitch occurs is because the two operations, detecting a used a item and detecting which Pokemon is in battle, happen to share the same variable. The variable is 01XX91CF for Red and Blue, and 01XX90CF for Yellow. Use a Potion, and this variable is filled briefly by "14". Enter a battle, and send out a Pidgey, and the variable will become 24.
