I’m running the current jailbreak firmware. The “run cartridge” audio settings are set according to firebrandx’s “cleanest possible sound” for genesis. I’ll have to look at the audio settings and see if making any changes corrects it. If anyone has experienced this and found some settings to change, it would be greatly appreciated. It doesn’t seem like a missing sound channel effect which I had on original hardware and was most noticeable with skipped sound effects when collecting rings.
