Before working with the file, it is critical to verify it is a clean, uncorrupted "USA" ROM. This is often the biggest hurdle in ROM hacking.
The standard "Super Mario 64 (USA).z64" should match these hashes:
If your file does not match these hashes, you may have a corrupted ROM or a revision mismatch (Rev A or Rev B), which will cause patches to fail.
If you are looking to create a "repack," you are likely looking to apply a patch to modify the game. Here is how that process works:

B. Texture Packs (Graphics Replacements) If your "repack" involves HD textures: Super Mario 64 -usa-.z64 REPACK
This identifies the game as the seminal 3D platformer developed by Nintendo EAD. It was the flagship launch title for the Nintendo 64 and is widely considered one of the most important video games ever made, establishing the grammar for 3D character movement and camera control.
