Pokémon PureRGB is a purist's enhancement of Pokémon Red, Blue, and Green built on the pokered disassembly. The project's philosophy is simple: improve replayability and quality-of-life while staying strictly within the bounds of Gen 1 — no imported mechanics, moves, visuals, or Pokémon from later generations. Just a definitive version of the games that already existed. All 151 Pokémon are obtainable in every version of the hack, with rebalanced stats, improved movesets, and expanded move availability for historically underserved types like Bug, Poison, and Ghost. Front sprites have been curated from the best available across Red, Green, Blue, and the Spaceworld 1997 demo. Some Pokémon have revised typings — Ninetales, for example, becomes Fire/Ghost — though these changes can be reverted through an in-game NPC at Indigo Plateau. HMs are deletable at any time, with softlock prevention baked in. Classic Gen 1 quirks are largely preserved by design. Mew is still under the truck, Missingno and the item duplication glitch are intact, and exploitable battle engine bugs like Hyper Beam's no-recharge-on-faint remain untouched. The one exception: Missingno no longer corrupts your save. New content includes Cinnabar Volcano (built from unused map data), a custom Poké Ball designing system in Cerulean City, gym leader rematches post-Champion, trainer clubs for leveling underleveled Pokémon, and several post-game secret areas expanding on Team Rocket and Mewtwo lore. The Pokédex has also been significantly expanded with a MOVEDEX, unlockable learnsets, and town map wild Pokémon data. A robust options menu lets players toggle a wide range of visual and mechanical enhancements, including switchable color palettes (original, Super Game Boy, or Pokémon Yellow), full Game Boy Color support with colored move animations, optional Spaceworld 1997 back sprites, cut-content music like Giovanni's theme, stereo audio panning, an in-battle experience bar, adjustable type matchup tables, and region-based alternate-color Pokémon. Most of these features are off by default and must be enabled in-game.
