Not sure if this helps you but few things to keep in mind....

Add this line to your game.txt, located in your seplugins folder:
Code:
ms0:/coderPR/coderPR.prx 1
Remember to check if its enabled in recovery mode.

If I remember correctly CoderPr doesn't use the default nitepr folder to load it's cheats, so anything you have for nitePR won't show up in your cheat menu. To add cheats to CoderPR, simply drop your nitepr txt files into:
ms0:/coderPR/cheats/

Extra Note: If you start experiencing errors with the searcher/the plugin:
Open up the /temporary/ folder inside of the coderPR folder, and delete any files you see inside.
Also, you may want to try deleting psid.bin if you've updated recently.
