My code input won't work. HELP ME !!

[pasywasy]

I have Action Replay for DS and sometimes it doesn't reconise the game but it works when I put my game code in. When I put my Animal Crossing:Wild World's code in to the original heading it doesn't work. When I try to put it in the bottom screen goes red and turquoise. HELP ME I don't know what to do!

sounds like something went wrong with the code input. Do you have the master code? Have you tried it with other DS games?

[pasywasy]

I tried the code with the other games and it works.
I tried some other codes with the Animal Crossing game and it still went turquoise and blue so its just that particular game.

[sparksmf]

okay. So that means it's not on the AR's end. Perhaps you are entering the wrong codes. Like you went to a site that gave out the wrong things.

What happens if you play the game without any codes? Does it run normally?

[pasywasy]

Yes the game run normally.
I tried the codes that worked on the other games and it still flashed with colours. I know my games code by putting it in and if it doesn't regonise it it gives me the code of the game.
