Topic: A secret code for NES Remix 2?

Nintendo tweeted out about 6 hrs ago this picture:

According to them, there is some kind of secret code hidden in the image. Another Twitter user and I think we may have the solution, BUT... I don't own NES Remix 2 so I can't try it myself. The other user suggested that the red letters are an anagram, which lead me to START SELECT A R using all of the letters from STAR TEST CLEAR. My idea is that you should press Start+Select+A+R after the credits have rolled and you see this message.

So... Does anyone want to try this out and tell me if I was right?

Yes, I can confirm it works. It's on the records option at the bottom the remix 2 selection of games, if you've unlocked it.
