Most Kanto ROM hacks pick one lane: bigger Pokedex, harder battles, or a new story. Pokemon Ultra Violet just tries to let you catch everything. It’s a FireRed hack built around a single idea: one save file, every Gen 1-3 Pokemon, no trading required. That sounds like a lot of ROM hack marketing until you actually look at what LocksmithArmy shipped back in 2013 and finished a year later, at which point it’s less “hype” and more “someone actually finished the checklist.” If you’re looking for a Pokemon Ultra Violet download, the short version is: this isn’t a new region or a difficulty overhaul, it’s still Kanto, just with the Pokedex door left wide open.

What Is Pokemon Ultra Violet?
Pokemon Ultra Violet is a Pokemon FireRed ROM hack created by LocksmithArmy, first released on PokeCommunity in February 2013 and marked complete in its 1.21 update, with a small 1.22 follow-up that only touched save compatibility. It keeps FireRed’s Kanto map, story, and gyms intact. What it changes is what you can actually catch: instead of the vanilla 151, Ultra Violet folds Generations 1, 2, and 3 into one FireRed cartridge, using version-exclusive swaps, non-trade evolution workarounds, and a new optional island so nothing is locked behind a second cartridge or a link cable.
It’s a completionist’s hack more than a difficulty hack. If you came here after Pokemon Radical Red looking for something tougher, this isn’t that. Ultra Violet is closer in spirit to “what if the original Pokedex just… didn’t stop at Kanto.”
Ultra Violet vs Vanilla FireRed
| Feature | Vanilla FireRed | Pokemon Ultra Violet |
|---|---|---|
| Catchable Pokemon | Gen 1 only (151) | Gen 1-2 in the main game, plus Gen 3 on 4-Points Isle |
| Starter selection | Pick one of three in Oak’s Lab | Pick one of three, or decline and catch your own starter instead |
| Trade evolutions | Requires a second cartridge and a link cable | Reworked so trading isn’t required |
| Sevii Islands | Gen 1 post-game content only | Gen 2 Pokemon added; Ho-Oh, Lugia, and Deoxys obtainable by island ticket, no Nintendo event required |
| Extra areas | None | 4-Points Isle (optional, Gen 3 encounters) |
Main Features
- Every Generation 1 and 2 Pokemon obtainable on a single save file, no second game or trading needed
- Version-exclusive pairs (like Oddish and Bellsprout on Route 24) both made available, so nothing is permanently locked by a version split that no longer exists
- All fossil Pokemon and the classic “needs a friend” fighting-types obtainable without trading
- Trade-evolution lines reworked to evolve without a link cable
- Umbreon and Espeon obtainable without relying on the GBA’s internal clock
- Mew placed at an early-game location instead of behind a Nintendo event
- Ho-Oh, Lugia, and Deoxys reachable through the Sevii Islands via an in-game ticket, again with no event requirement
- Raikou, Entei, and Suicune obtainable, tied to which starter you pick
- 4-Points Isle, an optional new area holding the Generation 3 encounters
- An option to catch your own starter instead of taking one from Oak’s three Poke Balls
Pokemon Availability & Pokedex
Here’s the part worth being precise about, because “catch everything” gets thrown around loosely on ROM hack sites. What’s actually documented: every Generation 1 and Generation 2 Pokemon is catchable in the core game and Sevii Islands on one save, with version-exclusive Pokemon and trade evolutions both handled so a single cartridge covers them. Generation 3 Pokemon are catchable separately through the optional 4-Points Isle area added in version 1.20. Community sources cite a combined total in the high 300s once all three generations are counted, though we’re not stamping an exact figure as verified since it wasn’t stated in the creator’s own documentation we could confirm.
Trading is not required to complete the Pokedex. Trade-evolution lines were reworked with an alternate method in place of the link-cable trigger, though the exact in-game mechanic used for each line isn’t something we could confirm line-by-line from primary sources, so treat that detail as community-documented rather than independently verified until a dedicated Pokedex article covers it.
Starter System
Starter choice happens the same way it always has in FireRed: Bulbasaur, Charmander, or Squirtle from Professor Oak’s lab. Ultra Violet adds one option on top of that. From version 1.10 onward, if you talk to Oak without taking one of his three Poke Balls, he gives you the option to catch your own starter instead. Community documentation describes this as a Safari Ball-based catching sequence, though we haven’t independently confirmed that specific detail against the creator’s own notes, so take the “how” with a grain of salt even though the “that it exists” part is solid.
New Areas & Events
The map is still Kanto, plus the Sevii Islands, plus one new addition: 4-Points Isle, added in version 1.20 as an optional destination holding the game’s Generation 3 encounters. Beyond that, the Sevii Islands themselves got Generation 2 Pokemon folded into their encounter tables, and the legendary birds/Deoxys unlock through a store-bought island ticket rather than a Mystery Gift event. There’s no second region and no rewritten main story here — the additions sit on top of FireRed’s existing structure rather than replacing it.
Legendary & Special Pokemon
The headline legendaries are all obtainable without a Nintendo event ticket. Ho-Oh, Lugia, and Deoxys are reachable via the Sevii Islands once you buy the relevant island ticket in-game. Raikou, Entei, and Suicune are obtainable too, with which one you get tied to your starter choice, according to the creator’s own notes. Mew is placed at an early-game location rather than behind an event, and shows up on the title screen as a nod to that. We’re keeping this section high-level on purpose — exact routes, level requirements, and step-by-step catch orders for each legendary belong in a dedicated Pokemon Ultra Violet Legendary Locations guide down the line, not crammed into an overview page.
