Just find the original you left on archive.org

Just in case you are still curious, and I don’t see any actual answers here. The download provided is all the code for the game engine and everything else that would be going on in the background of the game. Anything that could be copyrighted by Nintendo (things like character and object models, textures, music, and environments) need to come from a totally legit dump from an official Nintendo cartridge and definitely not any ol’ .rom file you can download online
