🛠️ User Guide

1. Open the archive

• Go to **File > Open** and select a `.rdb` file.
• The tool will automatically load the file list (please ensure that the associated `.rdx` file is in the same folder).
• Use the search bar at the top to instantly filter files by name or ID.

2. Extraction and modification

• **Extract**: Right-click any file in the list and select **Extract Selected** or use **Tools > Extract All**.
• **Modify (Inject)**: Right-click on the file and select **Inject New Data**. Select your modified files and the tool will automatically update the archive container.

3. Process Bin archive

• **Unpack**: Use **Tools > Unpack Bin Archive** to extract files from `archive_xx.bin`. This process generates a `manifest.json` file.
• **Package**: Use **Tools > Pack Bin Archive** and select the `.json` manifest file created when unpacking to rebuild the archive. The processed archive will be saved to the `Packed` folder.

4. Localization (modify text)

The localization process follows a specific multi-step workflow:

• **Unpack Bin**: Follow the "Bin Archive" steps above to extract the binary language files from the game's bin archive.
• **Convert to CSV**: Go to **Localization > Unpack Localization Files** and select the folder containing the extracted binaries. The unpacked CSV file will be placed in the `Export` folder.
• **Edit**: Open and modify the `.csv` file using any text editor or spreadsheet software (such as Excel).
• **Convert to Binary**: Use **Localization > Pack Localization Files** to convert the edited CSV file back to binary format. The new file will be saved in the `Result` folder.
• **Prepare to Rebuild**: Copy the original `manifest.json` into the `Result` folder, alongside your newly created binary language file.
• **Rebuild Bin**: Use **Tools > Pack Bin Archive** and select the `manifest.json` in the `Result` folder to build the final game `.bin` archive.
• **INSTALL**: Replace the original game files with your newly created `.bin` file.
