Description
Pokemon Emerald Squared is a fan-made ROM hack of Pokemon Emerald, focused on enhancing the game with double battles as a core feature. Built on the Emerald Expansion base and incorporating various community-made assets and features, the game introduces significant changes to Pokemon, moves, abilities, items, and trainers. It marks the first public release after nearly a year of development, with more documentation and updates to come.
Features
- Every battle and encounter post-saving birch is a doubles battle
- Tera and mega gimmicks both included at various stages of the game, along with ways to change tera types
- Many pokemon received buffs to stats, abilities, and moves, ranging from minor defensive buffs to total overhauls
- New abilities, moves, and items
- Buffed weak items like adrenaline orb, absorb bulb, cell battery
- Trainer party pools for major bosses (you never know what you’re going to get, have been told by my closed beta testers this makes hc nuzlockes quite difficult)
- Randomized fire/water/grass starters from 3 different regions offered
- A second starter gifted by birch after receiving the first
- Swap bikes with R
- Pokevial that gets progressively bigger as you beat gym leaders
- Every TM in Scarlet and Violet
- Every pokemon through Gen 9 available, with the exception of box art/680 BST legends, coming in patch 2.0
- Infinite Repel
- EV/IV editor
- Expanded and brand-new areas
- Updated battle backgrounds
- Side story that will later unlock a new area with box art/680 BST legends (area coming in patch 2.0)
- Super candies that level you up to the level cap
- Minimal grinding via two toggles for 0 EVs and perfect IVs
- And much, much more that i’ve likely forgotten over the past 10 months
Near-term plans (next month or two):
- Bug fixes
- Additional trainer slides mid-battle
- Box legends encounter area, rematches for side bosses and gym leaders
- Additional QoL and feature suggestions that are of minor undertaking
- Documentation for those desiring it
Long-term plans (early spring to late summer 2026):
- Additional areas and rebalancings
- Fleshed-out battle frontier with restricted/non-restricted vgc-esque formats
- More polishing before I move on to a more proprietary hack with a whole new region
Recommended emulators:
- mGBA
- Retroarch for mobile using mGBA core
Changelog
Minor Patch 2.4.3: Don’tcha know? It’s Sinnoh!
Bugfixes:
- Fixed a bug where celebi would potentially infinitely loop its ability
- Fixed a bug where sandsworn ground moves would miss levitating pokemon
Feature Updates:
- Added sinnoh pokemon to the battle frontier and factory!
- Added the Stellar tera type to the tera type changer in lavaridge. Whoops!
Balance Updates:
- Readded the debug menu. Beating wallace will tell you where the button to enable it is, and can also be accessed very early if you have the knowledge for subsequent playthroughs
- Removed AI_FLAG_OMNISCIENT from the smart trainer ai system. The ai should no longer know and play around your exact moves, items, and abilities without seeing them first, though a dumbed-down version called “assumptions” has been implemented. If it turns out that the AI implemented this way sucks, I will revert it.
Looking Ahead
Version 3.0 is planned for early to mid next year and will focus on updates to the Battle Frontier.
Before then, expect smaller updates to documentation, encounters, balance, and a new area for Regigigas.
Thank you all for playing, testing, and supporting the project. Enjoy the update and good luck!
