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

#1




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).

Bugs/notes:
- If the player captures a new Pokemon and has any Pokemon level up through capture experience, the PokeDex screen for the newly captured Pokemon will look glitched. This is a temporary graphical glitch, and does not affect gameplay otherwise
- Due to how the mechanics work behind Brick Break, Scrappy Pokemon that use it will still not damage Ghosts. However, it will still break screens (ie. Light Screen and Reflect)
- The animation for Draining Kiss may sometimes delay gameplay when used (possibly emulator dependent)
- New moves cannot be bred onto Pokemon (yet???)
