=>Fight Geese, the Hidden Boss: If you make it through the entire game and
beat Mr. Big without ever having lost even a single round of a match,
you'll face the hidden boss Geese.
=>Art of Fighting Data Import: On the Neo Geo home system, it was possible to
load a save file from the original Art of Fighting. If the AoF save was for
a game in which all three bonus games had been completed, then it would
import additional features/power in Art of Fighting 2.
At the moment, it isn't clear that this is possible on the Virtual Console
release if you have both AoF and AoF2.
=>Reveal King and Yuri's Femininity: If you beat either of these characters
and use a special attack as your final attack, their clothing will tear to
expose them as women.
