I need help with my action repay.?

i bought Animal Crossing Wild World from Ebay. the game was shipped from Hong Kong but is in english. i have practically beaten the game and i wanted to try out some cheats. so i used my action replay and it didnt register the game. i tried to input the game id but the cheats still didnt work. i was wondering if anyone knew a website that had the game id and codes that might work fr my version of the game.
