Nintendo recently launched the Nintendo Creators Program, allowing YouTube users to register with Nintendo so that they can upload videos containing Nintendo content and receive part of the revenue. If you register an individual video, you’ll get 60% of the revenue, whereas registering your whole channel gets you 70% of the revenue.
However, if your channel contains any non-Nintendo games on it (or any Nintendo games that are not on the approved list), you cannot register it. If you want to register your channel with Nintendo, you’ll have to delete any non-Nintendo videos. Otherwise, your only option is to register each individual video, forfeiting that extra 10% of revenue.
