Hi great hack thank you!

Does this have P/Sp Atk Split?






Can anyone say how to find Hoopa in mega power beta 5.59


Yo how tf can i play this game


you have to patch this game file to your pokemon emerald to get it to work, its essentially like an add on or a mod in a game.


Nice game, top of my list so far. But I hope the author fix the Pokemon Cries. Snover cries like zigzagoon, Abomasnow cries like a Tailow, etc. Hope it gets fixed though.


After defeating the first gym leader (Joel) how do I get to Klaus, I can’t use Cut without proper Gym Badge.
