Black Cipher

umm i just want to know how to get the save and load settings to work and how to use fly hack properly like sitting still

Alright, when you inject with the built-in injector,
You will need to put on all the hacks that you want in the menu [use arrows, ON/OFF],
After you'll need to go down the menu (at the end) and you'll see,
[Save and load setting].

For the fly hacks, you need to press [space] and jump at sametime,
I recommend not using it, since you have chances of getting it suspended [account],
Just use [Ghost mode] which your character will stay in place while you're in the air shooting other people, normally the key to use [Ghost mode] is ''X''.
