Issue with citra or maybe the Operating system

Issue:
Continuing the discussion from Citra error (Doesn't work):

Yesterday one of my friend (who own pokemon omega ruby.) Dumped the files into my macbook pro and told me that it should work flawlessly on citra canary, but when I went home and tried playing it, there was some sort of glitch in which the text was not at all visible and there were several colour blocks on the screen which made the game completely unplayable.

I don’t know if there is a problem with citra or my laptop or my friend have dumped the files incorrectly, because I was not present when he was doing it.

I would really appreciate some 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.

See if turning off Hardware Shader helps, it might become slower though.
