I'm guessing this has been posted in response to the recent article about the bsnes emulator. Interestingly enough, some bsnes forum-members have put some time and energy into exactly the sort of CRT-scanline emulation the article mentions at the end. For example, here's a GLSL shader that emulates CRT curvature, scanlines, and the Kell effect: https://gitorious.org/bsnes/bsnes/blobs/patches/snesshader/CRT.OpenGL.shader https://gitorious.org/bsnes/bsnes/blobs/patches/snesshader/C... ...and here's what it looks like applied to a screenshot of the Playstation game "Symphony of the Night": http://ind01.bilderkiste.org/2131284306277/SotN_crt.png http://ind01.bilderkiste.org/2131284306277/SotN_crt.png The original forum thread is here, but it's quite long and many different people post different implementations with different accuracy/speed trade-offs throughout its length: http://board.byuu.org/viewtopic.php?f=10&t=147 http://board.byuu.org/viewtopic.php?f=10&t=147
