Animal crossing codes

ok i just downloaded Animal Crossing Wild World for my AceKard...the codes for it dont seem to be working...i downloaded the thing from GBA Temp and theyre codes arent working neither...am i suppose to like press certain buttons to activate the codes.. like if i wanted Infinite Bells do i have to hold a button?

hi im not sure how to use an acekard because i have an edge card but im sure you could look up on youtube how to get the codea working. i think you have you press a certian button it should say that next to the code. well i hope that i helped.

Do you mean the friend codes?. When yo go to the two dogs at the gate, or something else? :)
