Mariokart live home circuit, 2 players

[Chocolatepeanuts]

Hi, would love some advice, 2 DS have asked for this as a joint Christmas present. I thought to do this I would only have to buy a second car, along with a full game but on looking further it looks like I need to buy 2 copies of the software if they want to play together, is this correct? 🥺

Yes I believe so, do they 2 switches? This was what put us of buying it too, Mario is not a 1 player game!
