Nice. I do know the feeling of "not wanting to cheat" by using existing solutions, where's the fun in that...

My PAL decoder is in Matlab, and so slow that it's mostly useless (because not realtime), but convenient for trying things out with the data, since you're already in Matlab... but the real goal was the eventually reached PAL generator anyway. That even found a practical use as well.

I think you should publish!

By the way, if you ever feel the itch to go back to it, try adding PAL support. It's NTSC with a few fun twists, nothing mind-bending though. The most "advanced" part of it is the delay line (which in practice will just be a line of memory).
