Modifying the Menu

So I've been working on creating a custom background by altering the X and Y coordinates of specific features of the game and I stumbled across this in the C3 bank. There are 16 offsets per X and Y character sprite; however there are only 14 characters. It's as if Squaresoft was intending for 16 characters in the character select screen in the airship, but dummied out the last two.

Code:

X position of characters in character select screen
C3/76CA:    18
C3/76CB:    34
C3/76CC:    50
C3/76CD:    6C
C3/76CE:    88
C3/76CF:    A4
C3/76D0:    C0
C3/76D1:    DC
C3/76D2:    18
C3/76D3:    34
C3/76D4:    50
C3/76D5:    6C
C3/76D6:    88
C3/76D7:    A4
C3/76D8:    C0          (unless a character was put here during moving around, this is a blank spot)
C3/76D9:    DC          (unless a character was put here during moving around, this is a blank spot)

Y position of characters in character select screen
C3/76DA:    5C
C3/76DB:    5C
C3/76DC:    5C
C3/76DD:    5C
C3/76DE:    5C
C3/76DF:    5C
C3/76E0:    5C
C3/76E1:    5C
C3/76E2:    78
C3/76E3:    78
C3/76E4:    78
C3/76E5:    78
C3/76E6:    78
C3/76E7:    78
C3/76E8:    78          (unless a character was put here during moving around, this is a blank spot)
C3/76E9:    78          (unless a character was put here during moving around, this is a blank spot
