DON'T UPGRADE to v5.0.X for this, really don't please. It's not worth it. Wait for proper Atmosphere which will be 100x better.
OK, with that big WARNING above out of the way first, now onto the trending front-page Nintendo Switch Underground Scene News of the hour, for those loving to live on the edge of leading technology hacks, and got all their nipples wet and hard earlier today after seeing the 'teaser tweet and video' posted by @SciresM, you can now enjoy the same joy of shitting your homebrew pants, just don't come crying to us with your RCM 'battery issues' afterwards!

So there you go, if you love to live dangerously, you can check out the links above, but remember most 'homebrew' still only works on v3.0.0, but there is reports the 'Tetris' game does work with this 'temp launcher', but that is about it so far, so for now its best to wait!
