Nintendo classics such as Metroid, Zelda and Punch-Out appear to be all playable on the Windows Phone 7. The recent releases appear to be NES rom dumps and the games misleadingly use Nintendo images from recent Nintendo releases.
Nintendo have made it very clear that their games don’t end up on non-propriety systems. Nintendo President Saturo Iwata explicitly states Nintendo would not be developing for other platforms. Which raises the question why have they appeared on Windows phone 7?
