Description
This Emerald rom hack replaces the original game’s Pokemon with those from the Johto Pokedex (with some changes). The goal is to provide a new experience compared to the original Emerald game while maintaining the basic feel of a mainline Gen 3 game. It’s similar to a randomizer, but a little more intentional and cohesive.
This isn’t a difficult hack. I tried to keep the difficulty curve similar to the original games. Due to the increasing movepools and power creep of more recent generations, I have erred towards improving bosses’ parties and movepools to keep the original difficulty. However, it is still a Pokemon game; it will not be too difficult.
The author is looking for feedback before polishing and launching the game, so if the above seems like fun, give it a shot and leave your feedback on the game’s pokecommunity thread:)
Changes from the Original Game
The Hoenn Pokedex has been superseded by the Johto Pokedex. All Pokemon from the first 252 (Kanto to Johto, Bulbasaur to Celebi) are available, with the exception of Lugia, Ho-Oh, Mewtwo, Mew, and the regional legendary trios. Later-generation evolutions are also accessible (such as Leafeon, Magnezone, and Kleavor).
Pokemon have been placed in environments that make sense in terms of flavour and challenge. Trainer battles have also been updated to include Pokémon from Johto and Kanto. I’ve also tried to highlight and provide players the opportunity to employ Pokemon that aren’t always readily available in-game, while demoting some Pokemon that are extremely frequent in other games. However, my first objective was always to place Pokemon in areas that made sense.
Kyogre, Groudon, Rayquaza, and the Regi-trio retain their place within the story (in the place of Lugia, Ho-Oh, Mewtwo, Mew, and the regional legendary trios).
Regional formes are available in the post-game.
Features
- Full Pokemon replacement, with updated wild encounters and trainer battles
- Full Day/Night system. Overworld visible day and night, with different encounters in each.
This hack is based on the pokeemerald-expansion, and this hack includes the features provided with this base. I have kept the QoL features and updates (e.g. evolution methods) as they are implemented there, for the sake of consistency. See the README on Github for the full list, which includes:
- Physical/Special split
- Fairy type
- Updated damage calculations
- HGSS-style Pokedex
- Nature colors
- Running indoors
- Reusable TMs
- …and more
Many thanks to pret and everyone at RHH – working with this project was a dream!
While the updated battle engine has support for battle gimmicks (Mega-Evolution, Z-moves, Dynamax), these aren’t available within the game.
