Pokemon Silver Mirror ROM

Pokemon Silver Mirror is a GBC ROM Hack by Th3Element05 based on Pokemon Crystal in English. It was last updated on October 28, 2026.

Description

Pokemon Silver Mirror is a custom Pokémon game based on the Pokémon Crystal disassembly. My goal was to recreate the story of Red’s journey through Kanto from Pokémon Red/Blue, with as many Quality of Life and graphical upgrades as possible while still maintaining the classic charm of the Game Boy Color Pokémon games.

I also wanted to include a new post-game storyline in Johto, as a mirror to the inclusion of Kanto in Pokémon Gold, Silver, and Crystal. Challenge the Johto Gym Leaders for eight more badges, and climb Mount Silver to face the final challenges in the game.
