Can anyone who has successfully played RRSS on Citra please help?

The instructions included with the download all depend on having a physical 3ds for homebrewing.

I've googled the shit out of it but can't find instructions on how to play Rising Ruby on citra. There is a youtube video with a direct download in the description but i'm hesitant to use it because it could be utter system-infecting garbage.

Much appreciated, kind anons
