pokemon platinum cheats?

for pokemon platinum there are no cheats imbedded into the game, whereas pokemon pearl has em.
im tryin to get masterballs so how can i get the cheats along with the rom?

How are you playing the game? Emulator or Flashcart?If you are using a flashcart, go to cheats.gbatemp.net and download the latest cheat database. If you are using an R4 you will likely have to update to YSMenu to bypass the cheat database limit. Or modify the database using R4CCE and remove a bunch of the games until the Platinum cheats appear.

^Or, you can use r4bugfix2, a program which patches the _DS_MENU.DAT file which fixes the whole flaw of the R4DS firmware. http://home.usay.jp/pc/etc/nds/index_en.html
