How to use it?

Open existing data: Click on the "File", and then the "Open data" options in the menu toolbar. On the new window that popped up, make sure to select a directory (folder) that contains "BadgeData.dat" file and the "BadgeMngFile.dat".
Create new data: Click on the "File", and then the "New data" options in the menu toolbar. Make whatever you want, and set the NNID number to yours if you want it to work. (read down bellow to know how to do that)
Save data: Click on the "File", and then the "Save data" options in the menu toolbar. If you opened data, this will overwrite the old data. If you created new data, then it will ask you to save it to a folder
Save data to: Click on the "File", and then the "Save data to..." options in the menu toolbar. This will always ask you to save it to a folder

Make a badge: Click the "Create new badge" button, and on the badge info, type in any name and any quantity.

To add an image, make sure you import a 64x64px image by clicking the "Import image" button under the badge's preview.

Make a set: Similar to making a badge, but now you will need to press the "Create new set" button. If it gives you an error saying that you don't have enough unique badges for a new set, then that means that last set only has one badge, and that badge is the last unique badge. To fix this, you can either create a new badge or change the Starting Badge of the last set to its value minus 1.

To import an image, click on the "Import image" button under the set's preview. Make sure the size of the image you're importing is of 48x48px, not 64x64px. If you have any trouble with the app, please tell me what it is, so that I can help you!
