Unused sprites
Unused text that I'm not sure what was for. Possibly an earlier version of the auto guard menu.
It appears that letting players choose between a tag mode or a single character mode was planned at some point.
Whilst there is an "auto" mode that is used, as far as I can tell this manual text goes unused.
Apocalypse has an unused and unfinished special attack. If you hack the game to play as him, it can be done with QCF+SK. He will raise his other hand, which will transform into a weapon and emit energy, but it can't harm the opponent. The CPU never uses this move.
