About This ROM Hack
Pokémon Ultra Violet Version is a classic FireRed enhancement hack built with the goal of allowing a single player with one save file to obtain nearly every Pokémon from Generation 1 and Generation 2, plus later additions through special content. It keeps the original FireRed story and map structure but removes version exclusives, trade evolution restrictions, and event-locked Pokémon.
The hack plays like an unofficial “third version” to FireRed and LeafGreen, focusing on accessibility, logical Pokémon placement, and completing the Pokédex without trading.
Story Overview
The main story closely follows the original Pokémon FireRed storyline: you travel through Kanto, defeat Gym Leaders, challenge the Elite Four, and confront Team Rocket. Narrative changes are minimal, but events and locations have been expanded to accommodate additional Pokémon, legendary encounters, and new areas.
New event structures allow players to encounter Pokémon that were previously locked behind version differences, trades, or Nintendo events, integrating them into the world in ways that feel natural within Kanto and the Sevii Islands.
Key Features
- All Gen 1 & Gen 2 Pokémon Obtainable: Nearly every Pokémon from the first two generations can be caught within one game, removing the need for trading or version swapping.
- Removal of Version Exclusives: Pokémon that were split between FireRed and LeafGreen now appear together in logical locations, such as both Oddish and Bellsprout being available on the same route.
- No Trade Evolutions Required: Pokémon that normally evolve by trading now evolve through level-up, stones, or other in-game methods, making all evolutions possible solo.
- Both Fossils Obtainable: Players can obtain both Kabuto and Omanyte fossils in Mt. Moon instead of choosing only one.
- Both Hitmons Obtainable: After defeating the Karate Master in Saffron City, both Hitmonlee and Hitmonchan can be obtained.
- Scattered Starters in the Wild: The original Kanto starters can be found rarely in logical overworld locations instead of being locked to Professor Oak’s lab only.
- Event Legendaries Accessible: Ho-Oh, Lugia, and Deoxys can be obtained through in-game methods without needing real-world distribution events.
- Legendary Beasts Expanded Events: Raikou, Entei, and Suicune all become obtainable through added events and locations rather than being limited to one roaming Pokémon.
- Sevii Islands Gen 2 Expansion: Generation 2 Pokémon that were previously unobtainable in FireRed are distributed across the Sevii Islands in fitting habitats.
- Sun Stone Availability: Evolution stones that were missing in FireRed, such as the Sun Stone, are now purchasable or obtainable, enabling evolutions like Sunkern.
- Catch Your Own Starter Option: A special feature allows players to skip choosing a starter from Oak and instead catch their first Pokémon manually.
- 4-Points Isle (Gen 3 Island): A new island added in later updates contains Generation 3 Pokémon and new events.
- Celebi Event Added: A special event encounter for Celebi was implemented in Berry Forest.
- National Dex Early Access: In the final update, players can obtain the National Pokédex simply by entering Oak’s Lab.
- Post-Elite Four Reset Skip Option: Version 1.22 added a method to skip the usual game reset after defeating the Elite Four for certain play setups.
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.
