Action Replay codes.
http://wiki.dscoders.com/index.php/Harvest_Moon_DS these are codes for harvest moon DS Also the action replay site is buggy( youll never find HM codes on the AR website) you can find most DS codes at that website (also i believe those codes work in the action replay)
You have to buy an Action Replay card.
Go to codejunkies.com for action replay codes, as it is the official AR website. These codes are the only ones which are guaranteed not to mess up your save file.Hope i was of help!:)
