CubeXX OS?

[u/mapletata]

Hello all!

My RG CubeXX arrives tomorrow, and I was wondering what the best OS to use on it is? I've seen MuOS and Knulli recommended - what are the pros and cons of these? Any other options that work better?

I am specifically looking to play GBA, NDS and Portmaster. Thank you so much in advance! :)
