Today, I went to load a game at random on my Sharp X1 Turbo Z, but I was greeted by this huffy horse:

The kanji character in yellow and red means “prohibited”, and it doesn’t allow me to continue from this screen, so I think it’s probably an anti-piracy mechanism.

I’ve named her Uma, the Copy-Protection horse, and I’ve grown kind of fond of her, but unfortunately I can’t remember which game caused her to appear.
