The following branches maintained by contributors can be a good starting point for your hack, or can be merged into an existing codebase.

How to apply a feature branch

  1. Add the repository as a remote on git: git remote add <name of your choice> <repository url>

    The URL you use is the same one you use when cloning the repository (so it should have .git at the end).

  2. Pull the specific branch you want: git pull <remote name you gave earlier> <branch_name>

pokeemerald Expansion

Maintainers: ROM Hacking Hideout

More of a hack base than a "feature branch". The Expansion overhauls and expands pokeemerald with many modern features, including:

  • An overhaul and upgrade of pokeemerald's battle engine with newer gen features and mechanics, such as:
    • Physical/Special Split
    • New and Updated Move Effects, Abilities and Item Effects
    • Fairy Type, Mega Evolution
    • Double Wild Battles, Custom multi-battles, Smarter AI
    • Ability pop-up messages
    • Mid-battle trainer messages
    • And more!

  • Pokemon from future games backported to pokeemerald.
    • Most Pokemon have two frames of animation
    • 6 colors in icon palettes instead of 3
    • Base stats, forms, and evolution data, including new evolution methods
    • Hidden abilities
    • Updated Pokedex, entries, Cries for Pokemon
    • TM/HM and Move Tutor compatibility

  • Most items from future games backported to pokeemerald.
    • All new berries
    • All new Poke Balls, including throw animations, descriptions, pics, catch rates, etc.
    • Evolution stones and Gen 7 potions
  • Many many many Configuration options for all of the above

Note: previously had three separate branches (battle_engine, pokemon_expansion, and item_expansion), but recently shifted to working only on the combined master branch and implemented a semvar versioning scheme.

For more information see pokeemerald Expansion's wiki.

  • Medicine (HP, PP and status recovery items)
  • Power-Up (Vitamins, Rare Candy and evolution items)
  • Battle Items (X items, Pokédoll/FluffyTail and hold items with battle effects)

For more info see this Pokecommunity post.

overworld-expansion

Increases the number of maximum object events in the game from 255 to 65535. This is done by converting the ID from a u8 to a u16.

free_saveblock

Maintainers: ghoulslash

Free up some saveblock space by removing superfluous saveblock data.

For more info see this Pokecommunity post.

To free up some more saveblock space, see this tutorial.

dexnav

Maintainers: ghoulslash

Adds a simplified DexNav, complete with Search and Detector modes, creeping up to wild Pokemon, and chaining.

For more info, see this Pokecommunity post.

dynamic-ow-pals

Maintainers: ExpoSeed

Adds a system to load and unload overworld palettes based on what is on screen, instead of keeping all overworld palettes loaded at once. This enables you to be much more flexible about overworld palettes.

Day Night Systems

Multiple people have implemented day night systems, and with various levels of fidelity and complexity.

Sierraffinity's DNS

(TODO: Add gif of player character waiting for nightfall in Rustboro)
Originally implemented for Crystal Dust, this system features hourly lighting changes (similar to Crystal), expanded encounter tables for nighttime encounters, and per-tileset palette overrides for window lighting. It only affects the overworld.

Samu/Xhyzi's DNS

(TODO: Add gif of player character waiting for nightfall in Rustboro)
This system features gradual fading between times of day, high customizability, and good documentation. It is the simplest to use, able to just be dropped in with minimal code changes. However it only does tinting changes, no changes to the encounter system, and the final effect may not be as high fidelity as the other implementations. Affects both overworld and battle.

Merrp's DNS

(TODO: Add gif of player character waiting for nightfall in Rustboro)
This system is the highest fidelity of these three, with semi-transparent shadows under every overworld object, inter-frame blending for glowing light effects, and per-color overriding for window lights. However, it is also the most complex system, and is still in active development.
Note: THIS IS NOT A CLEAN FEATURE BRANCH which includes only the Day-Night system like the other two; this branch also includes HGSS-style pokemon followers and a dynamic overworld palette system, among many other minor changes and tweaks to hundreds of source files. Merge at your own risk.
