My My Nintendo

My My Nintendo is an unofficial program adding statistics functionalities to My Nintendo, allowing to see an history of the actions done on the loyalty program in a chart or in an array, totals of points earned and spent, codes redeemed and received, ...

Using My My Nintendo

1. Download Greasemonkey for Firefox or Tampermonkey for Chrome, web browser plugins allowing to execute custom scripts on a web page.
2. Download the history recovery script and install it through the downloaded plugin in the previous step.
3. Go to My Nintendo and login to your Nintendo account.
4. An action bar is normally added at the top of the site. The "Recover a complete history" button will generate an history file since the Nintendo account creation, and sending an history file through the "Refresh an existing history" button will update a previously generated file with new actions done since previous generation.
   • Leaving the page while generating the history will stop it. Keeping the tab open is mandatory while the final file isn't generated.
   • In all cases, file generation may take time depending on the history size. Fifty actions are recovered every five seconds, a message in the toolbar will refresh depending on the steps done by the script.
5. After all steps, a mymynintendo_history.json file should be proposed to download. Send the file here to generate statistics :
   • The history recovery script doesn't store anything and doesn't keep any data. Keeping the history file by yourself is mandatory if you wish to use it later.
   • The history recovery script redeems all history data collected by My Nintendo, but the program doesn't use them all. So it shouldn't be necessary to regenerate a new history file after each My My Nintendo update, data are already recovered.
