Time adresses not changes, i tested. With it you can make like "Freeze game time" or else.
P.S. Code, that i posted, is for C#, i dont know what program language you use.
They may don't change at you , but on every machine they are different.
You need to find out the offsets with pointer.
But it's bit harder in GTA as i understand it, because the values are not saved like in "normal" games as normal values they are also saved in parts and it's harder to search them.
@Cal
I realy like your work and i am sure you will figure it out
I also don't think that there is someone in that community who realy can/would help you.
