It happened 2 days ago, Nintendo started taking down Mario hacks and videos done using emulators and such.
I really don't trust them anymore even for a short video, so sadly you won't see anything on my channel being Nintendo related. With that said I privated all my Nintendo 1st party games videos, especially SSBB music/texture hacks and NDS videos which were done on emulator only because I didn't know back then any way to record from a real NDS. I also trimmed all the Wii menus appearing from 3rd party games.
Fortunately my most viewed videos were all about Kingdom Hearts and old school games which were not by Nintendo. I'd say except a Kirby video and a DKC Tropical Freeze boss run which had many views, anything else has around 100/400 views and I'm not taking the risk.
It really upsets me only because of the fact I wanted my channel to not be a one game channel but to have an huge library of videogames. Nintendo made most of the very popular series and I'll have to live without them.
What I hate the most is how they did that coincidentally with the release of Mario Maker. Let me say if it wasn't for hacks, they'd never thought about making it. I'm not buying it for sure.
What's funny it's I got initially partnered with a network which specified in Pokemon hacks, and they called me only because I made ONE video, which is even deleted now.
I know this makes people mad, but these days I kinda need ad revenue from my videos, and I can't stand Nintendo throw 10 Content IDs on a video where I used a 1 second Mario jump sound as a joke.
By now I'll try focusing on Kingdom Hearts until I'm done with all I wanted to upload from 2FM/BBS 2.5, and then I'll move to old school games like I always did, they just won't be Nintendo games.
Remember this doesn't mean I won't do 3rd party games like Sonic on Nintendo consoles.
