I didnt crack the demo, i just memory edited my skill points. I didn't try the level cap as there really was no need for that. Dual weild works at level 6 (did i see somewhere it is level 8 or am i mistaken). If you really want I can upload 3 new characters with the full skill trees and link them so you can play with the skills.
The windforce thing is just me, ever since blizzard banned me for 2 hours chest hacking, deleting my bugged magic find helm and my windforce I have wanted a weapon as ultimately uber as the WF was. Actually the amazon was godly in d2 pvp even with the buriza but the WF was just so much more stylish. Ever since I demand a WF from every game with bows
Also, i noticed somebody mentioning the "pause game whilst looking at inventory in single player" - this would be very helpful.
