Emerald & FireRed Nat. Dex Extension v1.1.0 by CyanSixFour
The original ROM hack designed for the IronMON challenge. A total of 1209 Pokémon up to Scarlet & Violet are available, including forms, and Pokémon from The Hidden Treasure of Area Zero DLC.
Currently uses Generation III moves, abilities and mechanics, plus a few Fairy type moves so that Fairy type Pokémon can have STAB options. Level up learnsets, the type chart, and each Pokémon's BST have been updated to reflect the current generation.
Originally released as a fork of the IronMON Tracker, it has now been retired and replaced by an extension for the core Tracker. Thank you UTDZac for the help!
