Shaders not working

[jestrogar]

I tried both scanlines and retro and they do not work at all. If I select a system and select an specific shader it doesn´t work.
I have tried witha raspberry pi 3b+ and a rpi 4 4 gb and nothing happens

Do i have to change something in config files

Many thanks

@jestrogar @xxx2 The shaders are working, see this topic:

Perhaps this topic will help:

But, I believe it is a configuration problem, can you test with a clean image of Recalbox, without other modifications?
