I know I'm probably slow on this. I don't feel like sifting through threads to find discussions about this, so here.

Some of the sprites look off, particularly the Unowns, Absol, Kingler, Greninja, Solosis, and Togekiss (There are probably more, but I did not see more). They have multiple menu sprites--reversed sprites. Like, they've been mirrored, but are in the same position.
Have these been confirmed to have any usage in the code at all?
