How to Install:

Make sure you have the latest version of the mod loader with the "MapDataSaveDataTweaks" Installed: https://gamebanana.com/mods/559777

drop the contents of the SSS Organizer folder in "steamapps/common/DRAGON BALL Sparking! ZERO/SparkingZERO/Mods/MapDataSaveDataTweaks"

Launch the Game and start any battle in free battle or training mode. This will create a new file in the MapDataSaveDataTweaks folder called "CustomStageList.json"

How to Use the Tool:

Reordering Slots:

Simply drag and drop the slots to rearrange them. Your changes will be saved automatically.

Adding New Slots:

New Stages Will be added automatically after you installed them and start a battle in any mode.

Adding an Image to a Slot:

To assign an image to a slot, save an image file and name it with the same ID as the slot, then place it in the "images" folder. This image is just to visualize it in the tool and has no effect in game. You can see a map ID on the bottom righ of the tool under the stage name or right click on a slot in the tool to copy the ID to your clipboard.

Notes:

I did not create the MapDataSaveDataTweaks. This is only a GUI to edit the .json file.
