I think there is a setting in citra to render at a native resolution. But then the games look tiny with a huuuge gap between the screens. That's why I've got a DSi XL from Japan. They are really cheap and easy to mod, while giving me a native resolution big screen.
EDIT: Oops, not citra. The homebrew BIOS, I forgot it's name. Luma something?
