Play Pokemon Yellow Upgrade Online

Pokemon Yellow Upgrade is a fan-made enhancement of the original Game Boy Color release, developed by enthusiasts rather than an official studio. It arrived during a period when players were modifying classic games to add color and small refinements, fitting right in with that do-it-yourself spirit. The game builds on the familiar journey through Kanto but polishes the experience in ways that make it feel fresh even if you've played the original many times.

You control a young trainer starting out in Pallet Town, with Pikachu following closely behind instead of staying in its Pokéball. Your main goal is to defeat the eight gym leaders and become the Pokémon champion, which involves exploring towns, routes, and caves screen by screen. Signature mechanics include the ability to obtain all three starter Pokémon—Bulbasaur, Charmander, and Squirtle—through in-game events without needing to trade, as well as Pikachu’s affection system, where its mood changes based on how you treat it. The pacing stays true to the original, though the added color and slight tweaks make the world feel more alive. It’s a comfortable, familiar adventure that still surprises you with its small improvements.
