Shaders causing issues about ppsspp

Thanks for making this issue, seems impossible to use shaders with the ppsspp core at the moment, only a few works but only in windowed mode.

You can't seem to mix shaders either, just a black screen.

I really hope they can find out what's causing this because I don't remember the old ppsspp core based off 1.0.1 caused these shader issues.

Well it works with hrydgard@7f30ab1 and RetroArch 1.7.1 on my end now.

Then someone has to merge the changes
@twinaphex
Could you merge the recent changes from ppsspp?

I don't think that's necessary at all, just download http://buildbot.libretro.com/nightly/windows/x86_64/latest/ppsspp_libretro.dll.zip and you'll be fine.

I guess I was a little bit unclear with my previous answer, that commit is already in the core thats why it says "RetroArch PPSSPP 7f30ab1" in RetroArch.

I have gotten psp-color.glsl and motionblur-simple.glsl to work just fine, even combined.

I see. I thought the changes were made at ppsspp side due to your reference. So i will try it out :-)

Been trying this out quite a lot now and the issue definitely seems to be completely gone at my end.

There was this minor visual glitch with Dracula X Chronicles at the title screen first, but it must have been temporary and have not came back since.

I only use psp-color and motionblur-simple anyway as you can tell from this .glslp shader preset:

shaders = "2"

shader0 = "shaders/motionblur-simple.glsl"
filter_linear0 = "true"
wrap_mode0 = "clamp_to_border"
mipmap_input0 = "false"
alias0 = ""
float_framebuffer0 = "false"
srgb_framebuffer0 = "false"
scale_type_x0 = "source"
scale_x0 = "2.000000"
scale_type_y0 = "source"
scale_y0 = "2.000000"

shader1 = "shaders/psp-color.glsl"
filter_linear1 = "true"
wrap_mode1 = "clamp_to_border"
mipmap_input1 = "false"
alias1 = ""
float_framebuffer1 = "false"
srgb_framebuffer1 = "false"
scale_type_x1 = "source"
scale_x1 = "1.000000"
scale_type_y1 = "source"
scale_y1 = "1.000000"

Only glsl is working. cg or slang still do not work.

Apparently .cg do not support OpenGL 3.2 or higher contexts so that's probably the reason .cg shaders won't work with PPSSPP.

As for .slang shaders I have no idea why it do not work, I suppose .slang shaders is Vulcan related and I stay away from Vulcan in RetroArch.

But PPSSPP does have a Vulcan renderer so I don't know?

I close it because shaders are working with glsl

Yeah I think that's the best thing to do at the moment and at least .glsl shaders work now.
