Recently I exported my Super Mario Maker 2 save data to look in which format the level files are stored and I found out that the files are encrypted. After a quick Google Research I found this program, which can decrypt the course data. https://github.com/simontime/SMM2Course ... r/releases
Unfortunately the program can only decrypt the course data, not re-encrypt them. So I would be very grateful if someone could write a script with which it is possible for me to re-encrypt the course data.
Here are same example files

Decrypted Course Data: http://www.mediafire.com/file/51z1qgx9o ... _file/file
