Reicast doesn't work with shaders

RetroArch Windows devices
#1

hello :slight_smile:

I play super street fighter 2x on retroarch, and without shaders it looks horrible. I can launch the game (either with reicast OIT and reicast default) if i set video_shaders to “false” in retroarch.cfg but otherwise i just have a black screen with the dreamcast launch sound. My bios files have the correct MD5 signature, i have Hardware context ON. Redream behaves the same.

Is this normal or is there a solution?

Thanks

what type of shaders are you trying to use? Cg shaders are known to have these sorts of problems on certain GPUs with hardware-accelerated cores. Try GLSL shaders instead.

I’m trying to use Sony PVM RGB shader from the Analog Shader Pack. I tried to use crt royale as well. Actually GLSL filters (such as easymode) do not work neither. Black screen with only the sound

Here is the log

#5

have you tried enabling ‘hardware shared context’?

EDIT: whoops, didn’t see you already have it enabled.

#6

It is already enabled.

More details: I tested with two other games (VF3 and Street zero 3), same results: with “video_shader_enable=false” the games launch correctly. with “video_shader_enable=true” black screen, reicast launches to bios (i can hear the cursor sound when i press the d-pad). With snes9x, no problem.

Thanks to Tatsuya79 on retroarch forums, the solution was to delete \RetroArch\shaders\presets\Reicast\Reicast.cgp
