The Advanced Generation Glitched Pokémon Center is a glitch where someone tries to heal their Pokémon when they have none.

In R/G/B/Y when you tried to heal at a Pokécenter with no Pokémon, you would have had glitch blocks covering the screen and the game either reset or became a pokecenter version of glitch city. This glitch also works for R/S/E/Fr/Lg, but it goes on forever and instead of glitch blocks there are Pokéballs and there is no Glitch City.

Procedure

1. Start a new game.
2. Have the walk through walls code on
3. Walk to the PokéCenter without getting a pokemon or battling a Pokémon without having the code max stats.
4. Enter the PokéCenter and heal your Pokémon.
