A new problem with nitepr

[nigadix]

I'm trying to get codes for the US version of resistance retribution.

I've watched about fifty youtube video's and read heaps of tutorials on how to install nitepr so I'm pretty sure i've got it right.

When i go into the menu during the game and look at the "cheater" section, no codes appear.

I have a text file in the Nitepr folder called UCUS-98668 with codes that I got from this website. I can enable all cheats via the music button, but no cheats are showing up in the menu.

I have tried changing the kernel from 1.50 to 5.00 m33 in recovery

I have version 5.00 M33-3
Fat psp
Playing the game through a Compressed .ISO
Rev k Stable of nitepr

I don't want these codes for online, I want them to muck around with my friends in Ad hoc.

Thanks in advance.
