I had a CDTV and a CD32, but I never knew the details about CDXL format, thank you! I just checked and it looks like ffmpeg supports it, bless. It looks like the simplest possible video encoding format you could imagine.
Yes, the reason I was doing it like that on the PC was for the same reason you mention -- using polygons probably is faster because you cut out a lot of math and branches (as long as the polys are large enough) and just drop down to blitting huge swathes of solid color into the frame buffer.
