Please help with no$gba...

I have been trying to play pokemon heart gold with no$gba 2.6a, and I am aware that you need a code to prevent it from having the black screen, but the thing is: type the code in where?????? (sorry im a n00b) I tried the cheats section but it didn't work... please help

When you open no$gba press F2 it will bring up the cheat section click add new and paste the code in the blank space after that click action replay DS and ok then double click to check the code and click ok every time when you open the emulator the cheat will always be uncheck you will have to manually enable it.

Go here for more information.
