Digimon Adventure (SNES)
Also known as: Digimon
Digimon Adventure is an unlicensed SNES game that likes to... "borrow" graphics from other sources.
An unused Motimon enemy can be found with the other enemy sprites. A mockup palette has been used.
A Bug's Life Leftovers
There are more than these.
At the very end of the ROM's graphic files are some leftovers from the pirated game of A Bug's Life.
