Where do you type in cheat codes in Nintendo Ds?
you need a action replay,put it in your ds,put your game in the slot , turn on your DS and your ds will be in cheat sequence tap the * in a green circle it will list the codes and at the top will be a thing that says “add new code”.And there you have it.(You get an action replay from any of the following resources,Ebay,Gamestop or Best buy and you get codes fromsites but my fav is neoseeker and Action replays normally cost at least $20.00).Hope I helped!
