HeartGold is nearly identical to SoulSilver, it's not worth $40 extra dollars to buy the exact same game for one virtual Pokemon. Perhaps you should offer something to trade. By the way, there are many people on animalcrossingcommunity.com that have a Kyogre and might be willing to trade. Also, it's not risky to have a hacked pokemon unless you hacked it. I have never once experienced a problem or set-back using Action Replay, though.
