Simply put, Pokémon Modern Emerald is a modernization of the original Pokémon Emerald game. This game includes all of the QOL features and improvements I’ve wished for since I first played the original game in 2005. Consider this a 2.0 update of the original game. This is not a “difficulty hack rom” and never will be. There are already plenty of good hack roms out there if you want a super hard version of Pokémon Emerald. The idea behind this game is to play it instead of the original “Pokémon Emerald”, especially for those who want a vanilla experience with more features like easy difficulty modes, turn splits, QOL features, new Pokemon, new areas, new rematches… and an extensive list of others want.

This hack is a “3rd generation hack” which means that it doesn’t try to imitate later generations, and while some features and improvements are included from later generations, this hack is essentially a 3rd generation game. Don’t expect that you can catch 900 different Pokémon or learn all the new moves of the later generations. This hack doesn’t include the “battle engine upgrade” or anything like that, but it does include some of its mechanics (such as the OPTIONAL split between body and special that appeared in Generation IV, or the fairy type).

There are 423 Pokémon in total, two from Generation 8 and three from Generation 9. At the start of the game, you can choose between two modes on the challenge screen. If you don’t touch anything, the same Pokémon will spawn as in the original Emerald, minus the exclusive versions. All 423 are available when Modern Spawns is enabled. The game also includes day/night spawns for both modes (although without Modern Spawns the difference is minimal and is mostly a rate change for certain species).

WONDER-TRADES are also available to complete your national Pokédex (all Pokémon except Legendaries are available for Wonder-Trade, and you are limited to 3 Wonder-Trades per day).

The hack has all of its features and will only be updated with bug fixes, if any. HOWEVER, update 1.3 has been released due to the encouragement and suggestions from the community. So I’m always open to new ideas. The game has been thoroughly tested again and most bugs have been fixed.

The source code is available on Github and bugs can be reported there or in this thread. The game is playable on any emulator (tested on: MGBA, DSTwo GBA Emulator) as well as on real hardware (tested on: EZ Flash Omega). Also check out Pokemon Emerald cheats.

Let’s call it my “Dream Emerald” version, but it just got even better!
