CWCheat 0.16 - What is it actually?

Hi,

I am feeling like a noob, but otherwise not and this is why I opened this topic.

I installed CWCheat 0.16 on my 3.03oe firmware, like it is discribed in the readme.

And now?

The readme has a huge list of stuff it can do, but it doesn't say how.
I started a psx game, but i there's no difference. Does CWCheat has an own menu? Is there a special key-config to access the menu?

The readme says, i can choose between 255 memorycards per game. But how can i chose?
When i am in a game, i just have the normal ingame saving. No other options, not even a single memorycard to chose. Is there a way to access the native PSX memorycard manager (like on the psx when no disk is inserted)?

Thanks for any help.

Do you mean the actual in game CWcheats menu?

If so, you just hold select during the game. You also have to activate the .PRX (I think) in the recovery menu.
