Individual .opt assignments for Zx Spectrum games do not work.

Hello, in previous versions of Muos, all the individual assignments for the ZX Spectrum games that I had saved in .opt format in the Muos/info/config/fuse folder worked perfectly.
Now, after updating to version 2508, the controls for none of the games work.
Does anyone know how to make them work now?
Best regards

I have the same question (and about zx spectrum opt files too!). I’ve found a small workaround. See https://community.muos.dev/t/understanding-new-retroarch-config-approach/1095
