NIS America talked a little about Nintendo's approve system for every game:
Jack Niida, NIS America: Actually, Nintendo... They don't really have an approval process, surprisingly. What we do is basically propose the game to them and they'll say like "OK, cool!" But the problem is Nintendo has a [tougher] standard for the final master approval, so if the game sucks at the very end they'll say like - "alright, get out of here!"
