Pokemon Emerald is the most popular base for GBA ROM hacks. Its engine, and the pokeemerald decompilation that modern projects are built on, has produced everything from story-driven adventures in new regions to brutal difficulty hacks and a full roguelike. This page groups the best Pokemon Emerald ROM hacks by play style, so you can jump to the kind of game you want instead of reading a ranking that pretends one hack suits everyone.
Every hack below is built on Pokemon Emerald according to its creator’s own release thread or repository, and each one links to its full Pokemerald page with version, status and patching details.
How to Pick an Emerald ROM Hack
- Want a new story? Start with the original-story hacks, led by Pokemon Glazed.
- Want Hoenn with modern Pokemon? Emerald Crest, Emerald++ and Theta Emerald EX keep the familiar story and add modern Pokemon or conveniences.
- Want a real challenge? The difficulty hacks range from hard with adjustable modes (Inclement Emerald) to extreme (Emerald Kaizo).
- Want endless replay value? Pokemon Emerald Rogue turns Emerald into a run-based roguelike.
Original Stories and New Regions
Pokemon Glazed
Glazed is the classic “new adventure” Emerald hack by redriders180. It swaps Hoenn for an original story set mainly in the Tunod region, with Johto and Rankor to visit as well, and a plot in which the Pokemon world collides with the real world.
Status: complete; the original project ended with Beta 7, and later builds (up to v9.1) are community-maintained.
Style: story-driven adventure.
Pokemon Resolute
Resolute, by 1158, is a sequel to the same creator’s Victory Fire. It takes you through the Sylon and Tyron regions and then Johto, and adds a Battle Department facility for postgame battling.
Status: complete, updated over many versions (latest v2.97).
Style: long multi-region adventure.
Pokemon Mega Power
Also by 1158, Mega Power builds its story around a special Mewtwo that can Mega Evolve without a Mega Stone, and it includes every Mega Evolution.
Status: the creator describes it as 100% complete, though releases are still labelled Beta (latest Beta 5.77, August 2025).
Style: original story centred on Mega Evolution.
Hoenn with Modern Pokemon and Quality of Life
Pokemon Emerald Crest
Emerald Crest by Aaghat keeps the Emerald story but opens the Pokedex up to Generations 1 through 9. It also adds an in-game randomizer and an Open World mode.
Status: released and still updated (v1.0.F, June 2025).
Style: expanded Hoenn with modern Pokemon.
Pokemon Emerald Plus Plus (Emerald++)
Emerald++ by mynameisPooky is built on the pokeemerald decompilation. Its signature feature is that any Pokemon in your party can follow you in the overworld.
Status: finished (v10.1); the creator only plans critical fixes.
Style: enhanced vanilla Emerald.
Pokemon Theta Emerald EX
Theta Emerald EX by LCCoolJ95 is one of the older hacks on this page. Its main draw is that all 721 Pokemon from Generations 1 to 6 can be caught in Hoenn.
Status: complete (2017).
Style: classic Hoenn with a full Gen 1-6 Pokedex.
Pokemon Ephemerald
Ephemerald by shibarianne reimagines Hoenn through 382 new regional forms, called Sapphosian Formes, which change how familiar Pokemon look and play.
Status: released (v1.0.1.1).
Style: familiar story with unfamiliar Pokemon.
Difficulty Hacks
Pokemon Elite Redux
Elite Redux is a decomp hack built on Inclement Emerald. Its defining mechanic lets each Pokemon run several abilities at once, which changes team building completely. It is installed through the team’s official web patcher.
Status: v2.65 Beta, marked complete by the team and still updated.
Style: hard, strategy-heavy.
Pokemon Inclement Emerald
Inclement Emerald by Buffel Saft is a difficulty hack rebuilt from scratch on the pokeemerald decompilation. It offers three difficulty modes and custom Mega Evolutions such as Mega Milotic and Mega Flygon.
Status: playable (v1.13), with further additions planned by the creator.
Style: hard but adjustable.
Pokemon Run & Bun
Run & Bun by dekzeh is a hard difficulty hack of Emerald, and it ports in many modern move animations.
Status: complete (v1.07).
Style: hard difficulty hack.
Pokemon Emerald Kaizo
Emerald Kaizo by SinisterHoodedFigure is described by its creator as the super hard mode of Pokemon Emerald. Trainer teams are far tougher and items cannot be used in battle, so only held items help you.
Status: released (v2.0).
Style: extreme difficulty for experienced players.
Roguelike
Pokemon Emerald Rogue
Emerald Rogue by Pokabbie turns Emerald into a roguelike on the pokeemerald decompilation. Each run picks your routes, encounters and items procedurally, and a hub area keeps permanent upgrades between attempts. It comes in EX and Vanilla versions.
Status: released and maintained (latest release v2.1 on the creator’s GitHub).
Style: run-based, high replay value.
