Ocarina of Time was a landmark for Nintendo 64 hardware, pushing the limits of storage at the time.
Expansion: While initially planned as a 16 MB title, it was expanded to 32 MB to accommodate the massive 3D world of Hyrule.
Compression: The raw binary data is roughly 25.7 MB. However, when stored as a standard .z64 file or a decompressed baserom, it occupies exactly 32 MB of space.

The final part of the filename hints at the technical limitations of the era. The Nintendo 64 cartridges maxed out at sizes much smaller than today’s games. The standard for a massive title like OOT was 32 megabytes (or 256 megabits).
Looking at the sheer scale of Hyrule Field, the number of NPCs, the intricate dungeons, and Koji Kondo’s legendary soundtrack, fitting all that into 32 MB seems impossible by modern standards. This ROM represents a triumph of software engineering.
The developers used ingenious compression algorithms (specifically Yaz0 compression) to squeeze the entire world onto that chip. When you load this ROM into an emulator, you are witnessing a masterclass in code optimization. Every byte was earned. There was no "day one patch" to fix issues; the code had to be squeezed perfectly onto that 32 MB space, and the few bugs that slipped through became legendary.
