Has no one heard that this is going to happen. Nintendo is working with apple to port some titles to the iphone via itunes. Its not clear yet how the button layout will work, but it is sure there will be a D pad. Its talked about at this link.
Err...I'm biggest worry is the button lay out(plus the whole illegal ROMS etc).....I'm not sure if there is enough room for button, and a large picture. The design you have seems to close for me.
Then there is the no feedback, with many gamers want to feel.
Nintendo games required only two action buttons, so with multi-touch screens, the buttons don't have to be visible at all. Now I know some of you will say "but then won't your thumbs block your view of the game?".... but try this out...upload this photo on your iPhone and feel it out as if the old nintendo controller were invisibly superimposed over the game screen, and you'll see that it's actually not that bad:
