Big Heads
To activate the big heads option in the Options Plus menu, you must fight 100 matches in the VS or Arcade modes.

Honey's Bonus Outfits (Japanese)
To access Honey's bonus outfits, defeat the game on the Very Hard setting in Arcade mode. These outfits are selectable in Vs., Training, and Team Battle modes.

Invisible Walls
To activate the invisible walls option in the option plus menu, you must succesfully perform 350 MOVES in the training mode.

Knock Honey's Skirt Off (Japanese)
Defeat the game in Arcade mode on the Very Hard setting. After defeating the game, you can knock Honey's skirt off when you knock off her lower armor, revealing a lovely "Aeon Flux" G-string.

You can only do this in matches played in Arcade mode, and selecting another mode will cancel out the code, but as long as you stay in Arcade mode, you can still do it, even if you lose, choose another character, or play a two-player match (just not in Vs. mode!!). You must redo this code each time your Saturn has been turned off.

Hint: This will work even with "No Damage" selected.

Options Plus
To get this menu, you must beat the game in normal mode or harder with any character
