issues with golden sun Dark dawn AR Codes

ok, i have tried different codes but none of them work, could anyone help me on this?

Depends on the region of the cart(or rom) you're using.
Some codes need a (M)master code to function, other times it's using (E)European codes on a (U)Americian cart.

well the codes are from GBAtemp and i got no response from them so i was hoping something from here :)

can you explain the problem better? is it freezing when trying to open the cheats? or do you activate them and dont work

i have them activated but nothing happens with them

Most likely the wrong region as I said. That or you're missing a master code.
Try making sure what your cart region is, and check out the codes to see where they come from.
North Americian is U- E is European- J is Japan.
Those are the top three as far as games go.
If you're using a E code on a U game, it won't work at all.
