About This ROM Hack
Pokémon Sun Red is a highly expanded FireRed ROM hack that reimagines Kanto with a strong focus on Alola-inspired content, Gen VII Pokémon integration, and massive gameplay system overhauls.
Unlike simple difficulty hacks or minor edits, Sun Red aims to fully modernize FireRed by introducing:
- Alolan forms
- Gen VII Pokémon and mechanics
- Over 400 custom moves
- Deep evolution system changes
- New type interactions and battle logic adjustments
At its core, the project is designed to give players a fresh but familiar Kanto experience, where classic FireRed exploration is combined with modern Pokémon mechanics and a heavily expanded roster.
A major design philosophy of the hack is variety and flexibility in team building, allowing Pokémon that were previously underused to gain new identity through custom moves and evolution adjustments.
