How to use CWcheats in JPCSP?

[tuxzz]

Explain how to use please cheats that they were activated in games.
I did so:
Chose game, loaded to it, then went to the menu of codes, entered them in the field, ticked off ON\OFF, began game.
But they weren't loaded into game. All remains without changes.
Has then downloaded base has inserted into a program directory, but it too hasn't helped.

Look here !
