==================================================
a. Graphics Data
==================================================

The Silence spell graphic is comprised of a 6x6 matrix of 8x8 tiles (SNES 3BPP).

The following tiles are used multiple times in the FF3us Mute graphic, mirrored
as necessary:

HiROM Tile #
------- ------
D3/01F8 0x0015
D3/0540 0x0038
D3/06A8 0x0047


In FF6j, the corners of the Silence graphic use this tile (also found in the
FF3us data):

HiROM Tile #
------- ------
D3/04E0 0x0034


Most tiles from the FF6j version have a corresponding localized tile in FF3us.
FF3us Mute graphic tiles have been replaced with their FF6j counterparts as
follows:

Source Destination

HiROM Tile # | HiROM Tile #

The FF3us version of the graphic uses 4 fewer unique tiles than the FF6j
version. The other tiles in this data segment are shifted up accordingly,
leaving 4 tiles' worth of contiguous free space at the end.

The 4 FF6j tiles without FF3us counterparts have been copied into the free space
as follows:

Source | Destination
FF6j | FF3us (Modified)
HiROM Tile # | HiROM Tile #
------- ------ | ------- ------
D3/0588 0x003B | D4/C998 0x1311
D3/0A38 0x006D | D4/C9B0 0x1312
D3/0B28 0x0077 | D4/C9C8 0x1313
D3/0B70 0x007A | D4/C9E0 0x1314

b. Tile Map
==================================================

> Tile map for Silence graphic starts at D2/0080.
> Flag 0x8000 mirrors tile vertically.
