A couple more weird findings:
World of Warcraft inexplicably has a "James Bond" title screen buried in its graphics. Perhaps another game that uses the same engine?
Digimon Fighter contains yet
another variation on
Digimon Amethyst's title screen-- "Digit Dinosaur: The adventrue of devildom" (sic!). The subtitle is in the same font as Digimon Amethyst's, but the title screen itself is based on the
2003 Digitmon Sapphire variation, complete with Croc. (And no, this isn't an English title screen for the beat-em-up game-- the tile bank that it's in is straight out of the Mario-knockoff platformer.)
Edit: "Digit Dinosaur" may very well be the original title screen for that platformer, possibly - it has "Copyright © Design by BBD" as part of the tiles. Also, the Croc in the "Digit Dinosaur" screen is a more direct copy from the Croc 2 title screen - it was redrawn for Digitmon Sapphire.
