It doesn't. Almost Real switches from TEXT80 to SCREEN7 just a single time.
Or do you mean the skyline scroll in the title part? Instead of switching
between SCREEN7 to SCREEN5, I just doubled all the pixels... ;)

FD doesn't, AFAIK. It changes the page and the vertical scroll on a line
interrupt, but not the screen mode.

If you can find such a program, I would really like to hear it.
But I doubt there are many, maybe there aren't any at all. It is very
inconvenient to correctly display images in two screen modes that have a
different VRAM mapping. And using VDP commands is tricky as well, if a
command is executed during the switch odd things could happen.
There are games that change the screen mode on a line interrupt, but that's
between SCREEN4 and SCREEN5 (Space Manbow, Hydefos, Psycho World).
