Nintendo is famously protective of its IP. You cannot download a pre-patched ROM from a random website (that’s piracy). However, is generally considered fair use for preservation and modding. The code for the multiplayer mod itself is legal—it’s the Mario assets that are protected. Proceed with caution and respect the original developers.

The technical challenge of creating a split-screen Mario 64 is immense. The original Nintendo 64 hardware was designed to render a single viewpoint of the castle and its worlds. Asking it to render two independent viewpoints simultaneously—with two Marios, two sets of collisions, two camera angles, and two independent object interactions—would be computationally equivalent to running the game twice. The original console simply lacks the RAM and processing power. Therefore, the “ROM” in question is not a standard file. It is a heavily modified ROM hack, often based on the decompiled Super Mario 64 source code (a project known as SM64EX). These mods, playable on emulators or even real hardware with expansion paks, re-engineer the game’s core logic. They split the camera system, duplicate the player character’s state variables, and implement a rud form of memory management to prevent two players from corrupting the same world data.
