I have all (including Super Mario Kart on the Wii Virtual Console) but not Mario Kart Super Circuit for the Virtual Console on the 3DS. I just hope they will make an update on transfering 3DS Virtual Console from one 3DS to another, or make the Ambassador program games be available to the public. Because one of my friends has Mario Kart Super Circuit on his 3DS when I received his data from StreetPass showing it as the most recent game he played, I really love that game and I used to have it for the Game Boy Advance, and I don't know if transferring the file of the game from one 3DS system onto another 3DS will let me get the game onto my 3DS system and play it. Because I got my 3DS on my birthday, and I didn't became eligible to be an Ambassador to get it. So I don't know if that could work, or if they will do an update later on to make the Ambassador program games available to the public or transferring Virtual Console or Nintendo 3DS games from one 3DS system to another 3DS.
I have:
Mario Kart 64 (Cartridge and Wii virtual console)
Mario Kart DD! (Disk)
Mario Kart Super Circuit......(Man I hate this one) (Cartridge)
Mario Kart DS (Cartridge)
Mario Kart Wii (Disk)
Mario Kart 7!! (And Cartridge)
I'm just missing Super Mario Kart! I can always get it on the Wii virtual console but I just never felt like it.
I only have Mario Kart DS and Mario Kart 7 but sadly my R button breaks often like on my DSi so I can't drift on Mario Kart DS anymore and my R button is wearing out on my 3DS along with my L button!
I have Double Dash, Super Circuit, DS, Wii, and 7. I've probably played Double Dash and Wii the most out of those, since I enjoy playing Mario Kart with people I know, and most people I know don't own any of them. I've played Super Circuit the least.
Mario Kart 7 (Nintendo 3DS)
Mario Kart WII (Nintendo Wii) (I haven't played this in a while.)
Mario Kart 64 (Nintendo 64)
Mario Kart DS (currently my sister has the game now)
And that's it. I am hoping to get Mario Kart 8 for Nintendo Wii U.
