Getting Started

Use Dolphin to extract the entire The Legend of Zelda: Four Swords Adventures game disc into a folder. Launch the editor.
On first launch, the editor will ask you to locate data.arc. Select: files/GC4Sword/data.arc The editor will copy this file to its local data folder, so this step only needs to be completed once.
After the editor has started, open a stage archive from the extracted game files. For example, the first stage is located at: files/GC4Sword/Boss/boss010.arc

Changes can be saved directly to the stage archive.
Since Dolphin can boot extracted game folders, you can test your changes immediately without rebuilding the disc image!
