About This ROM Hack
Shin Pokémon Red, Blue & Green is an extensive enhancement hack for the original Generation 1 Pokémon games. The name “Shin” (真) means “true”, a term often used in Japanese media to describe a definitive or remastered version of something.
Rather than radically redesigning the original experience, this project focuses on repairing the original games’ engine issues while modernizing the experience with quality-of-life improvements. Over 200 bugs and oversights from the original titles have been corrected. At the same time, the hack adds numerous player-friendly features such as improved trainer AI, optional difficulty modes, rematches, shiny Pokémon, and expanded gameplay systems.
The project also serves as a research-driven reconstruction of what a polished Virtual Console re-release of Generation 1 might have looked like, if Nintendo had modernized the experience more aggressively. It maintains the classic feel of the original games while eliminating many frustrations that defined the early Pokémon era.
Story Overview
The story of Shin Pokémon follows the classic Kanto adventure from the original Generation 1 titles.
While the core narrative remains unchanged, the journey through Kanto is enhanced with additional mechanics, optional systems, and hidden secrets. Trainers may challenge you again through rematches, new NPCs offer additional gameplay features, and several post-game challenges expand the adventure beyond the original ending.
Despite these additions, the hack preserves the classic structure and feel of Pokémon Red and Blue, ensuring that the game still feels like a refined version of the original Gen 1 experience rather than a completely new ROM hack.
