NamePokemon Sigma Emerald


Pokemon Sigma Emerald is a hack of Emerald originally created by Tlachtli. It aims to be a game resembling a 3rd Gen remake de-make, with an unchanged storyline and upgraded mechanics. After a hiatus from mid-2014 to 2015, the project was handed over to me. For a rundown on the hack, the original thread can be found [here]. This is a continuation of the project, which began from Tlachtli’s last release.
