PROGRESS: Project Version 4.2c (COMPLETE) - 11/03/2026 - This is a fully completed ROM hack. The main story, including the sprawling island challenge, the Kanto/Hoenn journey, and all post-game Battle Frontier content, is finished and playable from start to finish.

It is a high-octane reimagining of the classic Hoenn experience, built on the advanced Dizzy Egg/Chacha Dinosaur battle engine. This hack breathes new life into the region by overhauling every single Pokémon—polishing stats, abilities, and movepools to make over 400+ species viable for competitive play. With a sprawling island challenge, complex story deviations like the Magma Base infiltration mission, and a focus on tactical combat, Altered Emerald is designed for trainers who want the definitive modern Hoenn adventure. Whether you are using the versatile nature switcher or mastering custom signature moves, this hack provides a polished, battle-centric journey that feels fresh from the first badge to the final fight with Steven Stone.
