Cheats won't work on Animal Crossing WW

For some reason whenever I put cheats on AC WW the game freezes up before I even start. Is there a way to fix this?

Try reformating your SD card or better yet replacing your cheat file

Nah, they don't work properly, however some new cheats work a little.

Some new cheats? Like?

I am also interested in these new cheats. :D

I always used cheats for this game (cause it's too boring waiting for stuff you need) and I never had a problem...try downloading the new ones from here http://cheats.gbatemp.net/

Gbatemp puts all the games together. It is easier if you use GBAtemp, but I like managing mine at codejunkies.com
