Memory Hacking Software

hello, I'm new to the forum and forgive my English.
the question is "how I can change in a flash game speed, but the stopwatch.
With the "cheatengine" could detect other games that are not time, for instance by values of "life" or "ammunition", but over time I can not.
Someone knows how to detect and change the data sent chrono?
And as slow time without changing the speed of the game?
Thank you very much: :D:D
