About This ROM Hack

Pokémon Ultra Violet is a FireRed-based ROM hack designed as a “third version” style expansion of the original FireRed and LeafGreen experience. Instead of drastically changing the story, it focuses on improving accessibility, completion, and Pokémon availability while keeping the classic Kanto structure intact.

The main idea behind the hack is to allow a single save file to obtain and complete both Generation 1 and Generation 2 Pokémon collections without needing trade restrictions or version exclusivity. It merges FireRed and LeafGreen exclusives into one unified experience while expanding encounter logic across the entire region.

The hack also introduces multiple quality-of-life improvements such as removing trade evolution requirements, improving Pokémon accessibility, and restructuring rare Pokémon locations in a more logical way. Overall, it feels like a definitive “complete Kanto + Gen 2” version of FireRed.


Key Features

  • Complete Gen 1–2 Pokémon Availability: All Pokémon from the first two generations are obtainable within a single save file without version restrictions.
  • Combined FireRed & LeafGreen Exclusives: Version-exclusive Pokémon are merged, allowing access to both sets in one game.
  • Trade Evolution Removal: Pokémon that normally require trading now evolve through level-up, stone, or alternative logical methods.
  • Eevee Evolution Accessibility Fix: Espeon and Umbreon evolution methods are enabled despite the lack of a real-time clock in FireRed.
  • Reworked Starter Distribution: Starter Pokémon are scattered across the world in logical locations instead of being limited to Oak’s selection.
  • Expanded Legendary Access: Legendary Pokémon such as Mew, Ho-Oh, Lugia, and Deoxys are obtainable through in-game events instead of external distribution.
  • Sevii Islands Expansion: All Gen 2 Pokémon not originally accessible are placed throughout Sevii Islands with structured encounter logic.
  • Mystic Beast System (Legendary Dogs): Raikou, Entei, and Suicune have dynamic encounter systems based on starter choice, adding replay variation.
  • Item Accessibility Improvements: Items like Sun Stone are added to Poké Marts to support full evolution availability.
  • Ultra Violet Event Updates: Special events and Pokémon placements are refined across multiple versions (1.10–1.22 updates).
  • 4-Points Isle Expansion (Gen 3 Inclusion): A new island adds all Generation 3 Pokémon, expanding post-game exploration.
  • Quality-of-Life Improvements: Includes catch-your-first-Pokémon option, National Dex accessibility in Oak’s lab, and improved save compatibility systems.


Known Bugs & Issues

  • Earlier versions had minor issues with Legendary Beast events, which were fixed in later updates.
  • No major unresolved bug list is officially documented for Version 1.22.
  • As a heavily event-modified hack, rare scripting issues may still occur, though no detailed public reports are available.
