About This ROM Hack
Yellow-ified LeafGreen is a small personal project — nothing too ambitious, just a tweaked version of LeafGreen that pulls some inspiration from Yellow while keeping everything else mostly untouched.
The changes are subtle: rival adjustments, encounter tweaks, reusable tutors, cheaper items, and a bit more resource accessibility. It's not trying to reinvent anything, just make the game a little more enjoyable to play through.
Worth noting, though — this is an unfinished demo. Content only goes up to around Cerulean City; there are text errors here and there, and some areas are still incomplete. It's a work in progress, so go in with that in mind.
Key Features
- Yellow-Inspired Gameplay Tweaks: Light inspiration from Pokémon Yellow, including rival changes and encounter design philosophy.
