Like MAME, MESS can use shaders to simulate typical CRT graphics artifacts such as scanlines, colors bleeding into each other, jitter, and display curvature. This involves editing mess.ini (or ume.ini if you use UME). Mess.ini works the same as mame.ini, so MAME tutorials can be used as a starting point. Some example configurations:*Windows: German tutorial (using the included HLSL shaders)**A scripted setup with separate "1980s" and "1990s" CRT configs: [http://shmups.system11.org/viewtopic.php?f=6&t=45026&start=240] (huge post is halfway down the page)**A German shader tutorial: [http://www.aep-emu.de/PNphpBB2-file-viewtopic-p-94168.html]*Linux: MAME tutorial for (using GLSL shaders): MAME tutorial [http://www.mameau.com/mame-glsl-shaders-setup/]. (Commandline and mess.ini option names are the same as in MAME.)
