Tutorials
This is a collection of handy modifications for pokeemerald. Modifications tend to range in both size and scope and cover all different facets of the games. The goal of this collection is to share resources among all fan-game developers while also showcasing to newer developers the ease and benefits of switching to decompilation-based projects. For feature branches you can pull from directly, please see the Feature Branches wiki!
This is intended to be a more sustainable version of the indexes that Avara and Anon822 maintained. Thank you both for all of your hard work!
If you would like to add a tutorial to this page, simply click the edit button in the top-right corner of the page. Further instructions will be visible there.
