I just did a windows reinstall and Citra reset my progress in my Citra games (Pokémon Omega Ruby and Ultra Sun), is there anyway to get them back?
In order for us to provide better support, we need to see the log generated by Citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File.
If you didn’t back up your save files, then they’re most likely gone I’m afraid.
You can try Recuva: https://www.ccleaner.com/recuva/download/standard if it doesn’t find the saves then it’s most likely gone. Remember to backup your files that you want to keep before doing a reformat in the future
What kind of file am I looking for here? A log?
