There's been no such thing as an UN-Patchable Hack, but IF you make a strong one, Kudos to you, :S
I agree with you too, it is almost impossible to make a hack that is un-patchable at all, I'm sure there is a loop hole around it. (even if its strong)
My friend is a white hat hacker and I think he can find a loop around it but still, sooner or later it will be patched, if you decide to upload it or not.
Please keep in mind that developers like x-trap, or punkbuster do this (patching hacks) for a living everyday, so I highly doubt it's 'un-patchable'
OT: You should release it, although hacks will get patched sooner or later ._.
ofc it will... -- making my self fly is the easy part.. and is probably staying the same ..the only thing is to make it "clever".. like something that the game it self will have to get me up in the air.. not changing my x.y.z
btw if the hack is clever enough to use the physics of the game to hack it can't get patched( unless they'r like reboot the game's engine roflmao)
