I'm using v1.21 of the GBA emulator with the gameconfig.txt in the right place. All of my GBA games run great, except there's one, little problem. Every second or so, there are these crackling, tinny noises that happen. They're mostly masked by the sounds of the game, but if you listen close, you can hear them all the same. I don't have any problem with sound when I'm running NDS games, so I was wondering if this is a problem with the GBA emulator or GBA game playback in general. Would changing any of the emulator settings fix this? I currently have them all set to the default. P.S. This is on a DSTWO with all firmware/EOS updates and a class-10 sd card.
