Hacking Action Replay Codes?

[thedeadman568]

First of all... hi everyone
I just joined GBAtemp and a gotta say... THIS SITE IS AWESOME
anyway right on to my question...
How can i use cheats for a ds game if the cheats aren't in the cheats.db?
Is there a way to enter action replay codes to use them with the game or something like that?
If the info is needed: the game i want to cheat in is Yu-Gi-Oh 5D's Stardust Accelerator
