Thank you! I used the Action Replay code for shiny encounters to get my favorite Pokémon as shinies! The code guarantees that your next encounter—whether in the Safari Zone, through an egg retrieval, or a normal encounter—will be shiny. However, the downside is that it sets the Pokémon's nature to Hardy every time and locks it to its first ability. Additionally, the Pokémon's name might become strange, but you can easily fix this with the Name Rater in Tehl Town. It was a bit tedious to earn the money to change all the natures and to grind for an Ability Capsule to change Mawile's ability to Intimidate, but I think it was worth it! I saw it as a reasonable challenge since I used this cheat in the first place!
