Extracting assets

Extracting files from the disc image first requires that the image is in GDI format. Different formats, such as BIN/CUE, must be converted first. Furthermore, current tools for rebuilding hacked disc images only support GDI output.

Requirements

• GD-ROM Explorer
• A utility to convert Dreamcast disc images to GDI format, if necessary. Examples include:
  • gdidrop (Windows)
  • gdi-utils (Multi-platform; uses node.js)

1. If your Sakura Taisen 3 disc images are in BIN/CUE format, use one of the tools above to convert them to GDI/BIN/RAW format.
2. In GD-ROM Explorer, open the disc.gdi file.
3. Create a new directory into which the files will be extracted.
4. In the left sidebar, right-click on IP.BIN and extract it to the directory.
5. Right-click on the ISO entry under IP.BIN and select Extract content of \ to... Create a new directory named data in the same directory that IP.BIN was extracted to.
6. Repeat this process with the other discs.
7. Make duplicate copies of all of the directories of extracted files. One copy will be your backups of the original files. The other is your working copy, on which you will do all editing and disc rebuilding.
