SARC Tool is a tool that can read and generate both big endian and little endian SARC archives, whether they are Yaz0 compressed or not. It is one of the few tools that are able to align file data correctly.


  1. Install the sarclib package. [CLI help]
  2. Install the libyaz0 package. [CLI help]
  3. Download the latest release from GitHub

Known issues

  • Unnecessary padding for BotW: SARC Tool may add unnecessary padding when archives are repacked, meaning generated archives may end up larger than the original even if no file size has increased inside the SARC. The game will fail to load it unless you fix the Resource system.
