At some point I got it to at least open() the relevant files but I don't know how, and now it's not even trying. I take the example from PluggableShader.txt: Code: sdlmame -gl_glsl \ -glsl_shader_mame0 /shader/glsl_plain \ -glsl_shader_mame1 /shader/custom/glsl_add_mamebm_bilinear \ puckman Throw in my rompath, and tag it with strace: Code: strace -o "\|grep shader" sdlmame -rompath /mnt/roothorick/mame/roms \ -gl_glsl -glsl_shader_mame0 /shader/glsl_plain -glsl_shader_mame1 \ /shader/custom/glsl_add_mamebm_bilinear puckman In the console output I only get one line: Code: execve("/home/roothorick/opt/bin/sdlmame", ["sdlmame", "-rompath", "/mnt/roothorick/mame/roms", "-gl_glsl", "-glsl_shader_mame0", "/shader/glsl_plain", "-glsl_shader_mame1", "/shader/custom/glsl_add_mamebm_b"..., "puckman"], [/* 51 vars */]) = 0 Uh huh. So it's not trying to open the shaders, or even see if they're there. Why? SDLMAME runs, the game boots, but no filters are applied, of course. What am I doing wrong?

The plot thickens:

Code:

sdlmame -rompath /mnt/roothorick/mame/roms -video opengl -gl_glsl puckman

== black screen. Same with sf2, but rsgun and s1945ii work.

So, trying the obvious:

Code:

strace -f -o "|grep shader" sdlmame -verbose -rompath /mnt/roothorick/mame/roms \
-video opengl -gl_glsl -gl_glsl_filter 1 -glsl_shader_mame0 ~/.mame/shader/glsl_plain \
-glsl_shader_mame1 ~/.mame/shader/custom/glsl_add_mamebm_bilinear \
s1945ii

Aaaaand... nope. Everything looks right in the console:

Code:

27518 execve("/home/roothorick/opt/bin/sdlmame", ["sdlmame", "-verbose",
 "-rompath", "/mnt/roothorick/mame/roms", "-video", "opengl", "-gl_glsl", "-gl_glsl_filter",
 "1", "-glsl_shader_mame0", "/home/roothorick/.mame/shader/gl"..., "-glsl_shader_mame1",

But the image is very clearly pixelated -- no bilinear in sight.
