The big catch is that Nintendo must approve of your game to give it their official Seal of Quality. They will test and debug your software, approve it or deny it on quality and stability, and (speculating on this point) probably also to assure that it will not pose a threat to sales of any of their existing titles. I have a feeling their criteria for approval/disapproval is very high and only indie titles with a very good production quality would be approved.
