Most of You Guys out there with Harvest Moon DS Have Harvest Moon Ds v1.1 wich needs different action replay codes. All the codes I posted are not mine, therefore I do not take credit for them. There are also way more out there I'm just putting a few up. Unfortunately there is not a v1.1 code for 60 or all the harvest sprites.
