This is interesting in a couple of ways. First, I think it was ruled in court that a developer could use the Nintendo logo in their game for an unlicensed game because it was necessary to make it work. Nintendo's legal trap backfired. In another case, someone made a knockoff system from the GameBoy which would play the same games. The games they released would show their logo, I think it was Game Fighter, but in the code it actually contained the Nintendo logo. Basically tricking the system into running a game with a different startup logo.
