Descargar Pokemon Zafiro Alfa — Randomlocke Para Citra

I need to address the legality of downloading ROMs. Emulators like Citra are legal, but ROMs can be copyrighted. Users should only download them if they own a physical copy. Then, step-by-step instructions on setting up Citra, finding the ROM, configuration settings, maybe some common issues like save files, graphics, etc.
