About This ROM Hack
Pokémon Ultimate Mega Ruby is a remake-style ROM hack based on the original Pokémon Ruby version, developed by Maddy Styles and co-developer Arvin Torrente. It was originally released in January 2015, with updates following shortly after in January and March 2015, improving balance and fixing multiple gameplay issues.
The hack is widely known for its high difficulty and expanded Pokémon ecosystem, offering a much more demanding adventure compared to the original Ruby. It includes Pokémon from multiple generations, Mega Evolutions, Primal forms, and a heavily expanded legendary roster.
The author note also indicates that the uploader is not the original creator, but shared the hack due to its quality and relative obscurity.
