You can't put them back on Emerald once they are migrated XD. You have to trade from whichever version they are on. Once they are off a 3 rd game there is NO WAY they can be put back on XD. I so wish it could happen XD.
I was actually thinking of re-transferring all my DLs over to emerald and sending them to Pearl. Most of mine are touched on Pearl, and I guess if I transfer over one or two, I might as well send them all so I'll have an UT collection. XD
How can you force yourself when you just need a motivation to do it. I would do it with mine but I never got the cable to do it. LOL I wish I could help you or even do it for you but we are too far away. XD.
It will take that long for 2 events? All you have to do is download to Emerald then clone them on Emerald and migrate right? That should only take 30 minutes right? One of my other friends with DL events does that in about that time but does not have the same ones that you have though.
