It sounds like the whistles from Yoshi’s Island in Super Mario RPG. It is unpleasant to hear, and it’s ruining Street Fighter Alpha 2, which is some kind of sin against the nature of gaming.
Lemme know. I have a ‘qsound.zip’ file in the same directory as the gamefile for Street Fighter Alpha 2. If this is incorrect, then that’s the solution, and I need to know the right filepath for the qsound file. Or I could be barking up the wrong tree, there. It could be an improper qsound file, or qsound may run at higher than 32000 hz and I cannot seem to change the sampling rate in the Wii port of RetroArch at all.
