Instructions

Before You Start

[!IMPORTANT] It is highly recommended that you turn off cloud saving for the game before editing save files and create your own back up

Step-by-Step Guide

1. Decrypt your save file using SuikodenFix

• Look for files named _decrypted_gsd2_Data*.json
  • Always backup your original save files first!

2. Upload your decrypted save

• Click the upload button and select your _decrypted_gsd2_Data*.json file

3. Edit your save data

• Navigate through the tabs (General, Battle Characters, Warehouse, etc.)
• Modify values as needed
• Use the Data Values tab as a reference for item IDs and names

4. Save your changes

• Click the Save button to download the modified JSON file

5. Load in game

• Place/overwrite the save file in the game directory
• Load the game
• Note: Sometimes you need to overwrite the save file twice, especially when modifying the most recent save
