Pokémon Ash Gray is a Rom-hack of FireRed by Metapod23.
Pokémon Ash Gray follows the events of Season 1 of the Pokémon Anime.
- Despite following the anime, the player can catch Pokémon that Ash never caught, like the Spearow that attacked Ash and Pikachu in the first episode
- It's also not necessary to release your Butterfree like Ash did in the anime (and the movie)
- For unknown reasons, bad eggs can appear in the storage boxes.
- Another glitch happens when switching Pokémon during the first battle with Jessie and James, your other Pokémon becomes invisible. This may be due to the fact that in the anime, Pikachu was Ash's only Pokémon at the time
- The game features content from banned episodes of the anime such as Beauty and the Beach, the Legend of Dratini (which were banned in America), and Electric Soldier Porygon
- The side story "Holiday Hi-Jynx" is available after the Porygon mission. as it was supposed to be in the original run of the Pokémon anime
