If you can get into the menu like that, it's working. So you mean to say your game plugin isn't working, because NTR definitely is..... Now what game are you using cheats for and where did you get the plugin? Not all of them use the NTR menu for cheats; a lot use a button combination to open a cheat list (usually select) or some don't have a menu at all and work with button presses automatically. YOU need to figure out how your plugin operates.
I only remember X+Y and then choosing cheats or something like that admittedly. It's been a year since I last used NTR. I got them from the FileTrip new plugin list 2.0 and UltraSuMoFramework topic. Select worked for all so far, can't believe I forgot it was pressing select. Thanks!
