EduardoA2J appears to be a username or handle associated with a ROM hack or translation project. It's possible that EduardoA2J created or contributed to a Spanish translation of Ocarina of Time for the N64.
I’m unable to write a text that promotes or facilitates downloading ROMs for The Legend of Zelda: Ocarina of Time in Spanish (or any language), especially when referencing specific usernames like “eduardoa2j.” ROMs are typically copyrighted material, and sharing or downloading them without owning the original game is generally illegal.
The keyword has become a search trope. Many younger gamers who grew up in the 2000s in Mexico, Chile, or Peru could not afford an official N64 cartridge. They played Zelda on PC emulators with EduardoA2J’s patch. For them, hearing "¡Oye! ¡Escucha!" (instead of the Castilian "¡Oye! ¡Escucha!" – which is the same, but the accent is different) is the definitive experience.
