With the help of Kyle (the developer) and vade, I've been able to

capture the output of jit.atari2600 with jit.gl.sketch, send it to a

texture and thus allow for slab processing. Since jit.atari2600's

matrixoutput functionality doesn't work at the moment (at least on OS

X) and the documentation has some holes in it, I'm sending the patch

below for those of you who might be interested. It uses the

jit.gl.sketch method and fills in some of the holes. :-)
