What do I do when it says to put main.dat?

@Ronizlo Please describe the issue in more detail and provide a screenshot if possible.

Do you have a hacked switch running custom firmware to dump your save file?

This program is a save editor, and main.dat is the primary component of the save file. You need to obtain it prior to using this program.

@kwsch @lottehime I figured out how to get on the software but was wondering how to save my changes when I'm done.

I was told to select "save changes" but nothing happens when I press it.

Once you've saved your changes, transfer the files back to your console and import the save data with the same app you used to export it.
