zzrtl is a filesystem management utility for Ocarina of Time and Majora's Mask. Filesystems are dumped and injected by way of the highly customizable scripts it interprets. It has built-in compression features, and projects built to my specification work on both original Nintendo 64 hardware and Wii Virtual Console.
Scripts for dumping and rebuilding OoT and MM's filesystems are available in this repo's script directory. Should you wish to tailor them to your project's specific needs, read the manual. Use a plaintext editor with C syntax highlighting for the optimal editing experience. For Windows users, I recommend Notepad++.
If you are looking for a dedicated compressor, try z64compress.
For beginners, the first paragraph of the manual is all you need to get started.
For advanced users looking for bleeding-edge functionality, check out jaredemjohnson's fork. It adds support for sound, music, and text editing.
The following projects were made using zzrtl.
