Ongoing OpenEmu development has seen a lot of changes recently. One of the exciting new features is leveraging Quartz Composer for post processing frames from the various console emulators using OpenGL. These filters allow high quality scaling using GLSL and whatnot. But a lot more fun can be had with the Quartz Composer backend...

This filter aims to emulate what gaming is like on an older CRT monitor.. literally. We borrow from Stellas new CRT emulation code, and build on it by adding iSight powered reflections in the CRT, and distortion to match the curvature of the tube.

This is just a relatively simply example of what can be done using Quartz Composer as a filter system, there are a lot more opportunities to have fun and adjust the output image to suite hard core tweakers and experimenters :)

Fun.

Just a sneek peak at an currently un-optimized filter/functionality.
