Intro

• This is a tool for both NEW and PRO modders for Zelda: Breath of the Wild
• SARC is a collection of files(nodes), usually in the form of ".pack" files for this game.
• Yaz0 is a compression algorithm, usually containing an ".s" at the beginning of the extension.
• You can easily read these file's headers using HxD, which is a free hex editor tool.
• This modding tool can help you take apart those files and put them back together to play and test!
• As for what to do with those files is up to you! Do research, look up a guide, join a community, and have fun with it!
