Zero Error is a minor glitch in Pokémon R/B/Y where the player causes a route to become glitched.

Procedure

1. Go to Vermillion City.

2. Walk up to the route north of Vermilion.

3. From here, do a Mew Trick variation by flying away from the trainer in the upper left hand corner of the route.

4. Choose to fly back to Vermilion City.

5. Walk to the route that is east of Vermilion.

6. Fight any trainer here. It does not matter who you fight.

7. After battle, go back to Vermilion and talk to anyone there.

8. Now walk up to the route north of Vermilion one last time: Voila, 0 Error. Effects can vary, from walking and hearing the Jr. Trainer, to seeing "0 Error" after bringing up the start screen. This has no other effect on the game, and you can Fly away to reset the route.

Notes

This can be done on any route where you fly away from a trainer before he battles you. You just have to do the above steps and walk back onto the original route.
