I have Windows 10 and just installed RetroArch 1.7.1 with Nestopia UE 1.49. Controls in menu work perfectly with my Xbox One gamepad but when I launch Super Mario bros. controls simply refuse to work. And there is also no sound in menu. I tried rebinding inputs, changing audio drivers. Nothing worked. I also tried other NES emulators but they all share these problems.
I’m having the same issue with 1.7.1. The only way I get any sound on any core is by using retrorch_debug.exe but with nestopia and bnes I can’t get my 360 controller to work. Should have kept my old version of Retroarch. At least everything was working fine.
For the controls thing, someone else having a similar problem said they fixed it by enabling “unified menu controls”. Dunno about the audio thing.
There was no problem with sound. I forgot that mario didn’t have sound in menu. So it’s only input.
