Even the peoples at Gameshark/Action Replay haven't figured out how to correctly make codes for this game! :D

You get:
Select=Expand farm, Always sunny, All animals happy, Inf. Lumber, Max backpack capacity, Inf. Stamina, Inf. Gold, Dog happy and healthy, Horse grown happy and healthy, Inf. race tokens, run really fast.

Remember to keep all codes de-activated until you have already loaded your game, then turn them back on and go into one of your menus to activate them!  :D
