Hello to all

I wonder how CE works. I have some problems need to be solved. Is it possible to do memory scanning to subsequently unlock something like items, hidden characters, etc. If so, how could I get it done?

Secondly, if a game provides ranks of something like S A B C, how can I scan memory for changing its level?

Lastly, how is it possible that CE can modify the memory to set hotkey for a game. For instance, I play PS1 using ePSXe. I'd like a game I'm playing to have a hotkey L1 that if pressed, an opponent's life point will become zero.

Is there any existing topic about this? If yes, please let me know the redirected link.
Or does anyone have any idea? Help me, please. Much appreciated

Very sorry about my terrible English T^T
