Re: Colossal64 Worklog
When the headphones are in, then the headphones get the audio from the game. When they aren't in, then the audio instead goes to those pins and you bridge them to mix the left and right audio because you only have mono with the PSone screen speakers. Then you connect it to the screen. If you don't wire that up, then only headphones will work and even with them out, the speakers will not.
