Question and maybe request regarding Shaders

[eadzon64]

Is it possible somehow, to add a custom Shader to Android Dolphin, and how?
there is a shader folder in my Android/ShieldTV installation of Dolphin,
but when i grab any own edited .glsl Shader from windows/desktop Version
and copy it there, it won't be recognized

I want to add a Zoom widescreen shader for letterboxed GC games
as described here,
https://forums.dolphin-emu.org/Thread-zoom-widescreen-shader-for-letterboxed-gc-games-like-resident-evil-4
to play Resident Evil 4 GC in full widescreen.

I do not really have the knowledge, so maybe you kind Devs could add
such a shader for Future Versions, please

thank you for your great work with Dolphin/Emu!

Thanks for reporting this problem. While the emulator core was capable of loading the shader, the Android settings GUI would not show the shader as an available choice. This should be fixed in the new version 5.0-14245.

Oh, thank you so much, it's working now
really fast and good support here!

Hey man,

How did you create the shader? What EXACTLY is the code? I copied the one from the link in a file that i named zoom.glsl...it is recognised by Dolphin, but as soon as i try to start the game with the shader ON, it crashes (works without it).

I've created the .glsl file on a PC now (previously i did it on my phone), and it doesn't crash anymore, but it says right when i start the game "failed to compile shader"...
Other shaders work well, even shaders from citra mmj, put in Dolphin - Shaders foldrr, are working without issues.

What am i doing wrong here guys?
