all that you need to do to add cheats is to make a cheat folder in your emulator folder. then look up cheats for either action replay or for gameshark and put the code in there. after your done adding codes then you have to save the document EXACTLY the same name as the rom, except the .gba needs to be .cht

this is just like a very brief explanation, but look at the readme in your download and your will find the proper instructions how to add it
