Good afternoon.
The situation/task/problem is as follows:
Game Star Wars The Force Unleashed II
Countdown timer hack.
Countdown value in "seconds" and "milliseconds"
Searched through
Scan Type "Value between..."
Value Type "Float"
I found “Address” between two values, but the process (timer) cannot be frozen, and when the value is changed and the value is returned to the game, the value is reset to minus the elapsed time.
The question is: how to freeze or add time to the timer.
