Then you forgot one of the following....
You
a) Didn't set what cheats you want on
OR
b) Didn't actually activate the cheats with nitePR by presing the musical note button...
dude i did activate them
when i pressed the music button i checked again and it says cheats wer on
also
the selected cheats wer white meaning they are selected
maybe its something to do with dma
the changing pointer thing
