While the ultimate issue is Nintendo’s IP, obviously you can’t remove Nintendo’s IP in this case since it’s for the N64, so the only other option is to remove valves. I understand why valve doesn’t want to implicitly endorse an N64 game with their IP by saying nothing, but if they remove valves IP then all that’s left is a generic N64 hobby project which Nintendo wouldn’t bother acknowledging.
