I joined this site to be able to comment! First, I must say great hack! I have been playing for about 2 weeks. Took a minute to get to work on my Xperia Play.
Now, I did find something odd. The egg I got from the Meteor Site had a Pichu in it, without Volt Tackle. When I went to Berry Forrest to get Lostelle, I saw the Celebi mirage, then when I went around the corner, the egg was there. Took a long time to hatch, and when it did, Jirachi popped out...
I have yet to beat the Elite Four, in fact, I haven't went through Victory Road, still leveling up before hand.
Again, great game! I even downloaded it on a friends computer to get him to play along.
