MAME can use shaders to simulate typical CRT graphics artifacts such as scanlines, colors bleeding into each other, jitter, and display curvature.
Some example The easiest way to do this (works on Windows, OS X, and Linux) in recent versions of MAME is to enable [https://github.com/bkaradzic/bgfx BGFX] video output: Put this in your mame.ini: video bgfx bgfx_screen_chains hlsl You should check with F11 if you get 100% performance with BGFX and if not, adjust frame skipping with F8/F9. Also, if you press the tilde (~) and then cursor up/down, you can adjust the shader settings. These are not saved at the moment though.[http://docs.mamedev.org/advanced/bgfx.html] Older methods are manual HLSL and GLSL configurations, here are some examples:
*Windows (using 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)
