put them in the same folder,
enable one at a time; while one is enabled, disable the other. You can do this in the recovery menu.
You must press home twice to activate nitepr, and you must do it when you see it flashing at the top of the screen.
Then you must hold "+ & -" at the same time to open the menu.

I'm not sure how Cheatmaster or CWCheat work.

so out nitepr in seplugins folder and thats it and itll start i thougt you needed cheetmaster also to use nitepr
No you don't need cheatmaster to use nightpr.
