Using Cheats

Hi, I have just set up RetroArch after I had been using stand-alone emulators for a couple of years. Everything is working fine though there is one problem neither my own attempts nor my Google research has been able to solve: How do I use cheats? I am using the bsnes accuracy core to play A Link to the Past and I have a cheat file which works with higan 0.93. Do I have to copy this file to the rom directory and give it a certain name or do I have to do something completely different?
