MagicX Zero 40: a Cute Little Vertical-Screen Console

I keep playing on my 3DS, there's nothing right to emulate correctly, there it's well thought out. The double triggers I don't understand the goal, the screen will be too narrow for other machines than the DS and the 3DS that won't make use of the bottom and since there's only one physical screen then we would have two huge black stripes. These machines more recent than the two laptops will be unplayable, so the extra triggers... Bof...
