Rev. 2.1 Changelist

 Other changes:

-Adjusted some code used by CPU players to reduce the slowdown,
 at the expense of some of the CPU AI, which might make this
 ROM Hack even more speedrun friendly. I tested this hack on a
 Mega Everdrive X7 through a Model 1 Sega Genesis yet again,
 to find that there is much less slowdown from CPU players
 getting dizzy now. It's not entirely eradicated, though, but
 it did help with the game's performance.

-The timer after both players choose their characters in
 Versus Mode is 15 frames shorter.

-The timer after a character plays their win pose is 12 frames
 shorter, making the time it takes to go to the next round
 closer to the Arcade.

Mai:

-Made a technical tweak to her stance animation.

-Stance Body Hurtbox is moved 2px back but expanded 7px
 horizontally, to match the sprite further.

-Stance Foot Hurtbox is moved 3px back but expanded 7px
 horizontally, to match the sprite further.

-S.LK's 2nd startup part uses a smaller Body Hurtbox, and
 the Foot Hurtbox from her Stance.

-S.LK stays active for only 3 frames, down from 6 frames.

-S.LK and S.MK each have 2 additional recovery animation
 frames.

-S.LK's active Body Hurtbox is expanded 12px forward.

-S.LK's active Foot Hurtbox is expanded 4px forward.

-S.LK's Hitbox is reduced 3px downwards, so it doesn't stuff
 Belva's low rush as easily.

-S.MK's 2nd startup part uses a smaller Body Hurtbox.

-S.MK stays active for only 4 frames, down from 8 frames.

-S.MK's active part uses the same shadow sprite as its
 recovery.

-S.MK's recovery is closer to Dhalsim's Far S.MK. It is
 much slower.

-All Far Crouching Punches recover 2 frames slower.

-Close Crouching Kicks' active Foot Hurtbox is moved 2px back,
 but is expanded 8px horizontally and 5px vertically.

-Far C.LK's active Foot Hurtbox is expanded 8px forward.

-Far C.LK's Hitbox is reduced 4px downwards.

-Diagonal J.HK's startup uses a more retracted Body Hurtbox.

-Diagonal J.HK's Foot Hurtbox is expanded 4px vertically.

-Back Dash uses one of her jumping Pushboxes, instead of a
 wide Pushbox.

-Kachosen starts up 1 frame faster.

-Chou Hissatsu Shinobi Bachi's horizontal movement is 1/8
 slower, making it easier to Guard Cancel punish. These changes
 were made in response to videos where they spam this move over
 and over again.

-Chou Hissatsu Shinobi Bachi's Head Hurtbox on its last active
 part is expanded 4px downwards.

-Chou Hissatsu Shinobi Bachi's last active part now has a
 Pushbox, allowing it to be Guard Cancel punished easily.

-Chou Hissatsu Shinobi Bachi's last active part does light
 stun, from medium stun.

-Chou Hissatsu Shinobi Bachi now has its own landing animation,
 so Mai can't attack immediately after landing from it. She can
 still juggle into S.HK afterwards, but it's harder to do now.

Emily:

-Moved the art of her 3rd stance sprite to a different location
 in the ROM.

Madonna:

-S.MP can now knockdown airborne opponents.

-J.LP can knockdown airborne opponents, at the expense of its
 overhead properties.

Belva:

-S.HK uses a more retracted Head Hurtbox while active. Said
 Head Hurtbox is also moved 4px down.

-Belva can now flight cancel G.LK at the end of a round.
