In the world of ROM preservation, verifying your file is crucial. Because filenames can be changed easily, archivists use hash sums to verify the contents.
If you have the standard, unmodified USA release, the SHA-1 hash of your file should be:

If your file matches this, you have a "Good ROM." This is the
Format: .z64 indicates a Big-Endian ROM dump, which is the native byte order for the Nintendo 64 hardware. File Size: Typically exactly 8.0 MB (8,388,608 bytes).

Released in September 1996 in North America, Super Mario 64 was the "killer app" for the Nintendo 64. Before this, "3D" in gaming often meant "2.5D" tricks like those used in Doom or restricted tracks like in Crash Bandicoot. Mario 64 gave players a true 360-degree playground.
The game’s development was so revolutionary that it was designed side-by-side with the N64’s hardware. Shigeru Miyamoto and his team realized that to move Mario in 3D, a digital D-pad wouldn't cut it. This led to the birth of the analog thumbstick, a standard that every modern console controller uses today. What Makes "USA.z64" Unique?
In the world of emulation and preservation, the .z64 extension signifies a "Big-Endian" format, which is the native byte order for the original Nintendo 64 hardware. While multiple versions exist (including the Japanese original and the later European PAL release), the North American version is often the "Gold Standard" for several reasons:

The .z64 file extension you mentioned is likely related to the game's ROM (Read-Only Memory) file format, which is commonly used for Nintendo 64 game data.
The -USA- tag indicates that this is the North American release (NTSC-U). In the vast digital archives of video game
While the Japanese version (J) was released first and the European version (E) came later, the USA release is the "Goldilocks" version for two massive reasons:
The "-USA-" tag is not superfluous. Regional variants of Super Mario 64 differ in subtle but important ways. The Japanese (J) version runs at a slightly different frame pacing due to the 60Hz vs. 50Hz power standards (though both NTSC). More critically, the USA revision (typically v1.0 or v1.1) contains specific text strings, controller pak save routines, and—most famously—the uncensored "So long, Kinga Bowser!" vocal clip. Later PAL and Shindou (J) editions patched numerous glitches, such as the Backwards Long Jump (BLJ), which speedrunners exploit. Therefore, the -USA-.z64 file represents a specific moment in gaming time: the launch-day experience of North American players in September 1996. It is the "wild west" version, bugs and all.
