I just dug out an old Will and started playing around with it. I put RetroArch 1.9 on it and I can load games and cores, but the Wiimote will not work in games. I can control the menus but no game functionality. If I change the default mappings, it will work.
Example - load up Super Mario World with SNES9x. The “+” is mapped to start, but it doesn’t work. If I change it to “B”, I can press start, but I can’t move or use other buttons. If I map DPAD Left to DPAD Right, and vice versa, I can move the opposite direction to what I’m pressing. If I change everything back, none of the controls work again. I didn’t try the remapping using MAME, but I had the same issue with no buttons working.
Also going into settings for a core to map buttons doesn’t work either. You get the timer to press the button you want to map to but it won’t take the input. Yet you can use the same buttons to navigate.
I also installed the 9/3 nightly and had the same issue.
Any advice on how to fix this?
