Dear Visitor
You can see what I offer in the pictures.
From your side i will need a little cooperation to get your save file.
1. You have to upload your save file via Nintendo Online service. They have a 7 day trial, you can try it for free.
System Settings-->Select Data Management-->Save Data Cloud Backup-->Select your desired savegame, press Y to update-->Back up and Save data
2. After contacting me and waiting to do my work, you can download your modified savegame in this similar steps:
System Settings-->Select Data Management-->Save Data Cloud Backup-->Select your user and save data, press Y to update-->Download Save data
Feel free to contact me about any game and welcome from Hungary
