Hi im new to MPGH

hi im new to mpgh but not new to hacking but umm im just think about bypasses when i think "what a bypass really is" and i didnt really know but i thought its just a engine that lets some hacks in but what if we got a engine from an older patch and make so it works with the current patch wouldnt that let in the old hacks just wonder i hope a pro could answer my question

I don't totaly understand your question but I'm going to try to answer.

A ByPass disables the protection from hacking.
So it does not matter whether It's new or old.
They still will allow to play the same hacks.

You can't just "get" an engine from an older patch, since if you executed combat arms, it would patch that Engine up.

A bypassed Engine like the one I made, it removes "A hacking tool has been detected", in the middle of a game so that you can freely hack all you want.
