0 ERROR

0 ERROR is a term used to refer to a glitch in Generation I of the Pokémon games. It causes the entirety of Route 6 to be filled with glitchy effects. It is most likely named after the 0 ERROR box that can pop up if the player opens the menu in Route 6 while the glitch is active.

Performing the glitch

Requirements

• A Pokémon that knows Fly or Teleport.
• If the player is using Teleport, the last Pokémon Center visited must be in Vermilion City.
• The northernmost Bug Catcher on Route 6 and at least one trainer on Route 11 must remain unbattled.

Instructions

1. Approach the Bug Catcher and pause the game when he notices the player as if performing the Mew glitch.
2. Use Fly or Teleport to return to Vermilion City.
3. Walk east to Route 11 and battle any trainer. The trainer must walk towards the player.
4. After defeating the trainer, return to Vermilion City and speak to any NPC besides the man with a Machop.
5. Return to Route 6. When the player enters Route 6, a message will appear, usually something that one of the trainers on Route 6 says before they are battled.

After the player completes these steps, the "0 ERROR" glitch should be active.

WARNING: The game should not be saved when performing the 0 ERROR glitch.

Effects of the 0 ERROR glitch

• Player moves very slowly
• Random glitchy noises
• The sprites of trainers on the route will flicker
• Player may be forced to battle trainers continuously
• Game freezes
