Nintendo ds animal crossing no shop uprgade

Not for the Wii. There is an Animal Crossing title in development for the 3DS handheld which is being released next year. Check out IGN's preview for it here: http://ds.ign.com/articles/109/1098788p1.html

I did not know friend code of the game animal Crossing

There are no cheats for Animal crossing on DS. The only way to get cheats is by buying an action replay. You can buy them on amazon: Here
Action Replay is like a DS game card, that has cheats for many different games on it.

well it might be the game it doesnt react good to your ds

Sorry, that's not true. You can save anywhere in the game by hitting the start button, whether or not you're in your house. To me, it sounds like your game file is corrupted. Your only option at this point is to start over again. If it doesn't work after that, you should buy a new game.

you must make sure that u enter then in action replay cerrectly

Try updating your software in your dsi? Keep in mind that AC was intended for ds not dsi so there is some bugs. Just like how AR(action ready codes) wont work for dsi, it just wasn't made for dsi.

solution? buy a ds? gamestop sell used ds for 70ish dollars or so.

Not possible

Its a glitch in the game i have the same deal. No Fix!

I suggest that you ask someone that has an action replay and ask if he had the same problem or just buy a new one.
