There was once a list of GBA games that had mobiclip/actimagine (since bought by Nintendo, and got to be quite commonly used on the DS and 3ds, but goes back to the GBA), which typically meant use in an intro video as opposed to intro in game animation or slideshow.
You might try finding that. If you are really bored then all mobiclip/actimagine games would have had a little logo appear in the title cards so you could possibly set an emulator to run, record the footage of the first however many seconds and then seeing if it has the logo in that (later games had a health and safety screen like the DS so you might have to press the start button a few times in this script).
There were a few other video codec type things made and some games used them, we did see a writeup of how it happened around here a while back though I am only finding an audio one right now.
