Pokémon FireRed and LeafGreen's biggest bug, the "roaming roar bug," has been fixed over 22 years after it was introduced, according to players. The bug, which removed Legendary Pokémon Raikou and Entei from the game, would have resulted in players essentially deleting Legendary Pokémon from their games permanently, making them permanently removed from their save files. This issue has been reported by players since 2004 and has led to many difficulties over the years. The fix was first reported by OmegaJarrodX in a post on X.
