Can a sleep button combo be implemented on lid close/open?

This is a feature that agb_firm apparently has and works with new sleep-patched games.

It would not do much without sleep on 3DS side but i will look into it.

Thanks! With that link I tested a patched rom on it and the sleep function essentially paused the game and resumed on the right button combo. It would just need to darken the screen and trigger on lid close to act the way it does on ds
