The Emerald patch should be really helpful
Thanks for all the amazing effort, everybody!
Kicking myself at the timing, just a month later and my Touhoumon hack would have had a Phys/Spec split.
As every move is customised and stat spreads and movepools of 67 are already done though, it'd be more effort than it's worth in a game already full of many unique features, I suppose.
But my third hack will really love this a whole lot, and it's all thanks to the persistence of the people involved in this thread!
