What Are Pokémon ROM Hacks?

A ROM hack is essentially a modified version of an original Pokémon game. Fans edit the base ROM file to introduce brand-new features such as:

• Completely original stories and regions

• New Pokémon generations not present in the base ROM

• Mega Evolutions, regional variants, and updated mechanics

• Quality-of-life tools like fast leveling, improved graphics, or custom soundtracks

Important: Always download ROM hacks from trusted and safe sources, and make sure you own the original game cartridge to stay on the legal side.
