There is no need to hack the game. Try trading over another Rage Candy Bar and try giving it to another statue. If that doesn't work,try breeding the Darmanitan. Breed about ten of them and you should have at least one Darumaka with the ability Zen Mode.
EDIT: You can also use the Royal Unova to get Rage Candy Bars but only on Saturdays.(Credit belongs to Crimson1)
Hope I helped,
