There’s a Mark III 3DS theme out. Looks perfect on a white New 3DS.
Now we just need some Mark III faceplates. It’s still crazy to me to see the Sega and Nintendo brands together like this, even after all these years of it being normal (the dual branded F-Zero GX launch screen was the first real time they co-branded, back in 2003!)
Check out the theme itself here:
