A '''{{wp|ROM hacking|ROM hack}}'''  is a modified version of a published game created by changing the code of the {{wp|read-only memory}} (ROM) to create something new. ROM hacks are popular among certain communities within the [[Pokémon fandom]]. Many Pokémon ROM hacks are {{pkmn|fan games}} created by modifying ROM dumps, disassemblies, or decompilations of the official [[Pokémon games]]. ROM hacks are typically considered distinct from [[bootleg]]s, which are unauthorised copies of published games sold to consumers.
