TSA/Tile Arrangement

All TSA data begins with a 12-byte header.

Bytes +$4-$5 indicate how many TSA tiles are in this TSA structure.
Byte +$6 indicates how large each TSA tile is in bytes by indexing to a table at 0x81AE280
Other values in the header are of unknown use.

Each TSA tile follows the usual GBA format for TSA:

Each TSA tile is two bytes; top nybble is palette ID; next two bits define flips:
+ 400   horizontal flip
+ 800   vertical flip
The remaining 10 bits index to the 8x8 tile graphics found in raw GFX data.

TSA in maps

All tiles in maps in Final Fantasy 1 are in units of 16x16 tiles. To construct these tiles, the game assembles two layers of 8x8 physical tiles, one for a background and the other for a foreground.

When given a Tile ID:

Take low 4 bits, multiply by 4
Take upper 12 bits, multiply by 256
Add together, add to TSA tile pointer
If map type is 0x1 and you're outside a room, add (0x1000); save result in r12
   This way, if you're in a room or not you'll load different GFX
load [r12], [r12+2] (top left/right of tile)
load [r12+0x80], [r12+0x82] (bottom left/right of tile)
Storing to tile map as 'background' tiles
load [r12+0x40], [r12+0x42]
load [r12+0xC0], [r12+0xC2] - These are for the 'foreground' tiles
