Animal crossing cheats not working on r4?

i have 2 r4 cards 1 is the r4i revolution for ds and the other is the r4i gold (clone) . i've downloaded the latest kernels and added the usercheats which work for most of the games on the revolution one but none on the gold. the one my kids want the most tho is animal crossing but although the cheats look fine when i use r4cee when its on the ds some of the cheats come up as symbols and blank spaces. i've tried using different usercheats but nothing works. please help!
