 18C3D            4    Initial positions. First 10 bits are the X position, next 10 bits are the Y position, 3rd byte is loaded into the first byte of the 7E8200 structure in RAM

Sprites

Mobs can have sprite IDs from 00-4F. In their default state, the sprite ID is mapped to a palette and graphics row ID, but in some states (sleeping, dead, invisible) their graphics will be overridden.|

Each graphics row is 200 bytes of tiles, stored as an 8x2 grid of 8x8 tiles in standard SNES graphics format.

Offset  Length  Item size   Description
------  ------  ---------   -----------
  2647      9E          2   vtable mapping sprite IDs to functions that handle rendering. 
                            Note these are stored as 16-bit little-endian pointers to the in-memory addresses of functions.
  4591      9E          2   vtable mapping sprite IDs to functions that update their animation flags.
  F159      4F          1   Palette index (0-7) of each sprite. Note that some render functions ignore this and use a hard-coded palette.
 16735      4F          1   Mapping of sprite IDs to graphics row IDs. 
                            The least significant 6 bits are an index into the row IDs table. 
                            The most significant 2 bits are the number of rows to load starting from that address: 00=1 row, 01=2 rows, 10/11=4 rows
 1679B      A8          3   Mapping of graphics row IDs to 24-bit in-memory addresses of the sprite graphics
