first you have to get the cheats (AR codes) then open your no$gba and go in other/cheats/add new/paste the ar code/name it/click on ar/then ok/then double click on the little check box
First you gotta find the cheats. Then you open NO$GBA emulator, press F2 (which is the short-cut key) or there is a menu button for you to press: Cheats When you get there, click on NEW Copy and paste (from the source of code), code is in the bog box, while the name is on the bottom. Then select what it is (Action Replay is the most popular) then you press okay. After that, you can activate cheats by pressing the cheats in the cheat menu and when there is a check mark, press okay and the cheat will be usable! I hope this helps!
