lmao no 1 is gona know what to do that that, and u dont either the god !
06-01-2008, 12:39 PM #4
put that into your game-save and you get hacks back !!!






PMSL i bet sum tries llf
06-01-2008, 01:22 PM #5
where do u put it i got it in my drive u mean the savegame?
06-01-2008, 06:16 PM #6
first of all gops i do but i choose not to. 2nd wtf game save are you all mental, its raw socket for packet injections.
06-06-2008, 02:53 AM #7
can you give us more of an idea on how to do this please

yea atleast a hint im not askin u to feed me but guide me thanks god

umm.. once you compile this im not sure what to do with it.

for those of you who think you put this into your gamesave, you dont.

go download Dev C++ compiler and compile this. just copy paste this into it and hit compile.

so what exactly does it do? it seems like pretty complicated code so maybe you should make this a little more noob friendly

it creates a raw socket
