I've actually completed the game, and have Shaymin, Heatran and the Manaphy egg ready to be transferred over... unfortunately when I try and transfer them over, it says "your request was turned down". I have no idea why this is happening, so if you're looking for the events I'm afraid I won't be of much help. If you want I can give it to you anyway...
If anyone has got around this problem, and has transferred them over, I'd love to know how. I've tried a US, EU and JP game for both platinum and Soul Silver...
