It may have to do with the removal of the music and sound effects, to my knowledge, the menu uses 48 kHz while the games/emulator uses 32 kHz, I don't know why it would have an impact, but something with the sound and how it was compiled has to do with the sound. The previous build from Askot didn't have this problem, however it never goes away with this. I hate to report this bug, because it feels like I'm nitpicking and showing ingratitude, that's not my intent, I just hope it can be looked into. But I know it's related to the audio.
So nothing can be done and looked into? I have no way of capturing the audio directly, I can only simulate the difference with audio frequencies and the tinny audio glitch.
The change here "Removed sound from GUI to get better performance/FPS on games like Yoshi's Island and Kirby Dream Land 3 (@Askot )" I believe is the culprit, because I definitely notice the tinny audio. I need
more people to test this, the Konami sound is way off and should sound clear, not raspy *sigh*
I'm sorry for bringing it up, I never should have.
My tests were in vain.
I could do a quick recompile to remove the no sound flag to test before doing anything else
