Mario Kart 7 is relatively new, and the software is more "hack-proof." They have not written software capable of hacking it quite yet.
UPDATE: Mario Kart 7 only works with Powersaves (developed by the same company as AR). Anything older is incompatible with not only MK7, but all 3DS games.
No.
not now, not ever.
No, but in Mario Kart 7, you can customize it.
On Mario kart Wii
Not unless they make an Action Replay for the 3DS.
first go to Mario kart channel in the game.then go down to the last selection and it will tell you if you want Mario kart channel.press A and then wait a few minutes and you will get Mario kart channel.
Well from how populare Mario kart was i think they will make a Mario kart 2 for wii so to answer your question probably yes!
There are currently 8 Mario Kart games:Super Mario Kart (SNES)Mario Kart 64 (N64)Mario Kart Double Dash (GC)Mario Kart Wii (Wii)Mario Kart DS (DS)Mario Kart Arcade GP (Arcade)Mario Kart Arcade GP 2 (Arcade) (Japan only)Mario Kart Super Circuit (GBA)
If you want to use Wi-Fi on either Mario Karts (Mario Kart Wii, Mario Kart DS) you must make sure you have a strong WEP connection.
Nintendo
Nintendo has no plans to make a Wii version of Mario Kart 7.
You must have action replay codes or must know how to texture hack into the game.
