All right, I named it wrong. I feel like a dumb ass... xD Thanks, Uncle FEEL.
EDIT: K, I guess I'm really stupid or something. I named it usrcheat.dat, I even tried USRCHEAT.DAT, usrcheat.DAT, put it in the dsone folder and I STILL can't get cheats. It's in patch mode and I have cheats turned on, yet I don't see any for any of my games... ;_; What else could I be doing wrong?
EDIT 2: Well I guess it would help if I dowloaded the usrcheat.dat instead of the cheat.dat.... >_> fml. Thanks anyways for all the help.
