About This ROM Hack
Pokémon Yellow Advanced is a long-running improvement ROM hack of Pokémon Yellow that significantly modernizes and rebalances the original Game Boy experience while keeping the core Kanto journey intact.
This hack focuses heavily on battle depth, expanded movesets, and modern Pokémon mechanics applied retroactively to Generation 1, while still preserving the nostalgic structure of the original game.
A major design goal of this version is to make nearly every Pokémon more viable through massively expanded level-up movepools, updated move effects, and rebalance adjustments inspired by later generations up to Gen 8 concepts. The result is a version of Pokémon Yellow that feels much closer to modern gameplay standards while still running on the classic GBC framework.
The hack also includes difficulty increases, expanded trainer teams, improved item economy, and updated wild encounters, making the entire Kanto experience more challenging and varied.
Key Features
- Massive Moveset Overhaul: Almost every Pokémon learns 1–3 extra moves at Level 1 plus many new level-up moves inspired by Egg Moves, Tutors, and future generations (over 553 new move additions total).
- Modernized Move Power & Types: Classic Gen 1 moves have been rebalanced to match later generations (Karate Chop = Fighting, Gust = Flying, Dig/Fly power updated, etc.).
- Higher Difficulty Trainer Battles: Gym Leaders, Rival, Elite Four, and many trainers use stronger teams, better movesets, more Pokémon, and evolved forms.
- Expanded Wild Pokémon Distribution: Every Pokémon can be found in the wild somewhere, with new encounters across routes, caves, and water areas.
- Economy Rebalance: Poké Balls, healing items, vitamins, and key items are cheaper, while rare items like Moon Stone and Ether now have proper shop values.
- TM Accessibility System: All TMs can be purchased in various Kanto Poké Marts.
- Game Corner Reward Rework: Pokémon, evolution items, and even Master Balls are available as prizes.
- Stat & Move Balance Adjustments: Draining moves, jumping kicks, and other attacks are brought closer to Gen 7–8 balance values.
- Legendary Level Rebalance: Snorlax, birds, and Mewtwo have adjusted levels to scale better with late-game progression.
- Mew In-Game Trade Event: Mew is obtainable without glitches through a trade.
- Geographic Enhancements: Routes are slightly expanded with decorative houses and environmental touches.
- Dialogue Improvements: Many NPC lines now include themes about friendship and life lessons.
