The Ultimate Guide to Super Mario 64: The .z64 (USA) ROM Format
The community has created thousands of custom games using Super Mario 64 as a base. Massive fan-made games like Super Mario 64 Last Impact or Super Mario 128 are built by modifying the original game data. The vast majority of these ROM hacks require a clean, unmodified USA .z64 ROM as a baseline to apply their custom patches. The Decompilation Project and PC Ports
Understanding the Super Mario 64 Z64 ROM for USA Systems The Super Mario 64 USA ROM in ".z64" format is one of the most important files in the retro gaming emulation community.

For the ultimate gameplay experience, the community has reverse-engineered the original source code to create native PC ports of Super Mario 64 (such as the sm64-port project). Instead of emulating the N64 hardware, these projects compile the game to run natively on Windows or Linux. This allows for true 60+ FPS gameplay, camera mods, and seamless dual-analog control schemes that feel right at home on modern gamepads. Note that compiling these ports still requires a legitimate USA .z64 ROM to extract the original copyright-protected assets like music, models, and textures.
Many enthusiasts argue for the "abandonware" status of older games, but this is not a legal defense.
