Actually I still check this forum every couple of months. But it seems I had not signed into my account for years.
The interlace screenshots are still online here:

It appears I still have some source code form the 400x400 pixels demo part I worked on in 2005. You can also see it in the screenshots above.
Manipulating the PAL signal should be easier today than it was ever before. You can get fairly cheap scopes that can capture an entire PAL frame at once to verify all the timing. I implemented the interlace code with an analog scope.
