Darkrai is the only one i've done so far. Also the only ones I really need are Darkrai, Celebi, Mewtwo, Arceus, Dialga, and Palkia. Mewtwo is already in though.
If you want to hear my idea for my hack, just tell me =)
Haha, I just went over the OW sprites you wanted me to do and noticed those are the only ones I haven't done. So, I'll put the Darkrai I just made onto it and a few other random Pokemon and send you the IPS back.
As soon as that's done I'll get working on OW's I haven't done.
