About This ROM Hack

Pokémon Uranium (GBA) is a Pokémon Emerald-based ROM hack inspired by the name and concept of the well-known Pokémon Uranium fan game, but developed as a separate GBA project using the Emerald engine. It should not be confused with the PC fan game of the same name.

This version focuses on building a new custom region experience inside the GBA format, introducing updated visuals, modified Pokémon data, and new scripted content. While still in a Beta 3 stage, the project demonstrates an early attempt at reworking Emerald into a more modern, custom-region adventure.

Public documentation is limited, meaning many gameplay systems and mechanics are not fully detailed, but the hack clearly aims to create a fresh standalone Pokémon journey rather than a simple Emerald enhancement.


Story Overview

The game features a new story set in a custom region rather than Hoenn’s original narrative. New characters and scripted events replace the standard Emerald plot progression. However, detailed story arcs, villain teams, and major narrative twists are not clearly documented in available sources.

The focus appears to be on delivering a fresh regional adventure with new exploration and character interactions rather than retelling Emerald’s events.


Key Features

  • New Region to Explore: The game takes place in a custom-designed region instead of standard Hoenn progression.
  • New Storyline: Story events and scripts differ from Pokémon Emerald’s original plot.
  • New Characters: Original characters are introduced, replacing or supplementing Emerald’s default cast.
  • New Tiles and Visual Assets: The overworld uses custom tiles and updated graphical elements to distinguish it from vanilla Emerald.
  • Custom Sprites: Pokémon and/or character sprites have been modified or replaced for a new visual style.
  • Updated Intro Screen: The title and introduction presentation have been redesigned.
  • Generation 4 Pokémon Added: Some Pokémon from Gen 4 are included, expanding beyond Emerald’s native roster.
  • New Scripts and Events: Custom scripting adds new in-game interactions and story triggers.

Known Bugs & Issues

  • Detailed bug documentation is not publicly available.
  • As a Beta 3 build, incomplete events, balancing issues, or graphical glitches may still be present.
  • Pokédex size, post-game content, and system changes are not clearly documented.
  • It is unclear how closely the game follows or adapts elements from the original PC Pokémon Uranium.
