  • Hack of: Emerald
  • Updated: September 9, 2018


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 (Alpha 3).

  • Poison status heals at 1HP and displays the “survived” message
  • Several abilities from Gen 4+ have been assigned to their respective Pokemon
  • In conjunction with new abilities, some Pokemon with one standard ability have their hidden ability as their secondary (eg. the Torchic line having Speed Boost)
  • Fairy-type added
  • Trade evolutions can now also happen by using a Trade Sim the same as an evo stone
