Hi Ozfalcon,
thanks for pointing me to the right direction !
After some fiddling I found out how to do it, it was some trial and error, but now shadow warrior looks exactly how i want it
I only use this setting for a handful of games that are too crisp , which is really a matter of personal taste in the end
Anyway, here's how i did it:
set you main mame.ini to write a game config when it launches a game for first time so it will create the shadoww.ini file in my case :
CORE CONFIGURATION OPTIONS -> writeconfig 1 (default is 0) (remember to put is back to zero or it will create an ini file for each game you launch)
When you launch the game now it will create the game ini-file , in this case : "shadoww.ini"
I Edited this shadoww.ini and changed these settings:
OSD video options ->video opengl (default is auto)
OSD PER-WINDOW VIDEO OPTIONS -> changed resolution to double the game resolution so i used 512x448
( this doubling was important as without it on original res, the blur/smoothing caused by the glsl filter was too much for me)
OpenGL-SPECIFIC OPTIONS-> set "gl_glsl" and "gl_glsl_filter" to 1 (default is 0 )
