Looks like my x86 Instruction Reference is working and at least somewhat optimized. I'll have to write up a page about how to add instructions to it so that I don't have to document all umpteen instructions myself.
I started work on glpong3d (a clone of the flash game curveball) in C and OpenGL a few weeks ago, but I'm just now putting it on the website.
SDLPong 1.4 has been released. Lots of improvements. No bouncing squares anymore.
