Gen III - Emerald Pokémon Sigma Σmerald [v1.914]


ROM Base: Emerald (BPEE)

Pokemon Sigma Emerald is a hack originally created by Tlachtli. It aims to be a game resembling a 3rd Gen remake de-make of the original Emerald, with an unchanged storyline and upgraded mechanics. After a hiatus from mid-2014 to 2015, the development of Sigma Emerald was handed over to me. For a rundown on the project, the original thread can be found here. This topic contains my continuation of Sigma Emerald, which picks up off Tlachtli's last release (Alpha 3).
