I found something useful for dark Dialga,it requires an action replay,try this 122AD628 00000228 it will change the first member of your team to Dark Dialga's skin,but will have the same stuff as regular Dialga,moves,ability,size,all except stats.This code will take effect next time you go to a dungeon,after you're done you can save it to keep Dark Dialga
*warning in the prosses of trying it use at own risk*
I'll give a report on my proggress later,but so far its a go.
P.S. to:moderators sorry for the long post
P.S.S. the moves need to be relearned at the link shop. Have fun with Dark Dialga
For those that see me on the outside,I pitty you.For those who know what I am,stay out of my way.....
