Wild Bits UI preview.png

Wild Bits can be launched with the wildbits command.[help] A desktop shortcut can also be made pointing to the executable in Python's Scripts directory.

The main Wild Bits interface has 3 tabs corresponding to its main functions: a SARC editor, an RSTB editor, and a YAML editor. Each editor supports both Wii U and Switch (big and little endian) formats where relevant and will automatically keep track of them. Each editor also automatically handles yaz0 decompression when loading, and will recompress on saving if the file extension begins with .s.

For more details on using Wild Bits, see the readme on GitHub.

Known issues

On some system configurations, launching with wildbits doesn't work and you must use python -m wildbits instead.
