For what do u need a speedhack ? I mean what game ?
Because i wont know how to do it in WarRock, but i do know it for CSS/CS1.6
Because ...
Css and Cs1.6 has SDK, so its easyer to do engine hooking
Dont even know if u can create a speedhack in D3D, for me, D3D is the bad side of life and C++/ASM the good side :P
