Nintendo has clarified the rules of its fledgling YouTube Creators Program for channels entirely dedicated to the scheme.
Any non-Nintendo videos on a dedicated channel will need to be removed for the channel to be accepted, the company has explained.
This ruling also applies to videos of games made by Nintendo but not part of the company's whitelist.
While a lengthy list, the rundown includes some confusing omissions (no Super Smash Bros. games at all, no Animal Crossing: New Leaf).
YouTubers who link their whole channel to the Nintendo Creators Program are eligible for a higher rate of revenue share (70 per cent per video), over videos submitted to the scheme individually (just 60 per cent).
Any user who has already submitted their channel for consideration by Nintendo has two weeks to remove videos of non-whitelisted titles.
Nintendo has also apologised for a slow start on approvals in general, something it blamed on a larger than predicted response.
"Thank you very much for participating in the Nintendo Creators Program," the company explained. "Due to your enthusiasm for the program, we're receiving a higher volume of applications to register channels and videos than expected.
"It is taking longer than we anticipated to confirm the applications. We appreciate your patience as we work through them as quickly as possible."
Nintendo's plans have received a mixed response from YouTubers since its announcement last week.
"They have every right to do this and any other developer / publisher have as well," top YouTuber PewDiePie wrote on his blog last week. "There'd be no 'Let's Play' without the game to play. And we (YouTubers) are humble to this fact.
"But what they are missing out on completely is the free exposure and publicity that they get from YouTube / YouTubers. What better way to sell / market a game, than from watching someone else (that you like) playing it and enjoying themselves?
"I'm lucky to be in a situation where losing ad revenue on a few videos wont matter. However, many people on YouTube are not in that situation. Everyone loses in this scenario that Nintendo has created, that's why I'm against it."
