[0xx-kyle-xx0]

ok, i got this code for unlimited ammo (thanks @mmbob)

0x373F7DC0
On: \xC2\x04\x00
Off: \x81\xEC\xB4

i took the code put it in notepad and turned it into a .dll file but what do i do now? just get an injector and inject it? , and can i inject this while injecting the blackcipher5?

and btw if this is in the wrong section can someone move it for me? sorry this is my first post,
