I have been trying to use Retroarch on the mi box and I have been having a lot of problems.

First, every time I move around the menu, the whole screen flickers black for a second.

Second, it slows down and crashes all the time on me.

Third, controlling it is really janky. Even when I set it to allow all controllers to control the menu, when I configure my Xbox 360 controller, it defaults to the Xbox controller and won't let me use my remote to navigate the menu and it makes the Xbox bumpers move up and down the menu.

Any ideas how to fix this or a link to a good config for Retroarch?
