I just downloaded an APK to my aNdroid device. Got it installed, running, and started playing Pokemon Alpha Sapphire (not important). I had been playing for 3 hours in total off and on. Ruining into lagging issues, which didn’t bother me. When trying to save the game, I received and “error 12” message, “unable to save file”. Game closed, I shut down the app and then I restarted my game to start from where I left off, but all my save data was deleted and I’m curious why it happened an where I can find my save data.
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.
How do I do this on a mobile device?
This is the yuzu support forum and you are asking about citra. Furthermore, there is no official citra android release so I don’t know that they will assist you with an unofficial release either.
