After building successfully, you can modify the source (C/assembly) and rebuild a new ROM — that’s how custom hacks like SM64 Star Road or OoT Missing Link are made.

Always respect copyright. Only use baserom.us.z64 if you own the original game and are working within fair use / personal archival rights. After building successfully, you can modify the source

It’s a byte-for-byte copy of the original US version 1.0 ROM of the game. The decompilation process uses it as a reference to extract assets, verify matching code, and regenerate a fully compilable ROM. Only use baserom

Decompliations don’t include copyrighted Nintendo code or assets. Instead, they provide a build system that expects you to supply your own baserom.us.z64 . The build script then splits it into object files and compares the compiled output against the original to ensure accuracy.

If you’ve ever looked at the source code for a decompliation project like Super Mario 64 (sm64) or Ocarina of Time (oot), you’ve likely encountered the file baserom.us.z64 .

You must dump it from your own legally acquired game cartridge. Search for “N64 ROM dumping” using a device like the Retrode or Sanni Cartridge Reader. No one can legally share the file itself.
