QR Code failed to be read

I am trying to play omega ruby a little while after completing the game I was running low on money. So a friend helped me and told about a lady who has a pokemon with happy hour and payday if you use a smeargle with sketch on it you can get both of the moves I opened my own secret base to scan it and later when I did the whole process for scanning it always( and I mean always) failed to scan the qr code
Please help

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 need AES Keys to be able to read QR codes. I’m not sure how to set it up (I haven’t looked at how to do it yet), but I know that QR codes don’t work on Citra without it

In configure, then camera, you can set what image to be what the “camera” sees. Somebody told me this so I can share my base.
