Progress saving

I can play new super mario bros 2 but when I last exited from game and again backed Im RAGED!!! I passed 3 levels but their progress literally deleted and I again must pass them. To this error not happen again, please tell me HOW TO SAVE PROGRESS???

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.

You shouldn’t, citra is a work in progress, expect issues, however…

Do you mean castles or levels, if i recall correctly, on most modern NSMB games you have to clear a castle to save your progress. i may be wrong on that.

3 levels in world 3. Its some sunny place with beach.
