Cheats/Exploits/Hacks are a little more complicated than that, im sure someone will be kind enough to search it for you... however, do understand.
Not like they hack it 1ce and we have Speed Hack for good... With every patch they have to re-compile the code and do it all over again. Also, why are you looking to use Speed hack?
