I don’t know why this happened, but the button Z in Beetle Saturn is now acting as an extra X. But in a way, it’s also completely disabled, because, in Street Fighter Alpha, when I try to map the attacks to each button, Z is not reconizable, but it still functions as X. I tried Genesis Plus GX and that one at least is working at it should. The controller is an 8bitdo M30 bluetooth.
Sounds like you remapped something in quick menu > controls
No, it’s mapped correctly. I had to change the controller to Dinput for it to work. Only negative aspect is that I can’t access the quick menu with the controller anymore, but not a big deal. Thanks.
