A level's particular graphics (tilesets & spriteset) are loaded into graphics slots $F0-$FC in the following fashion (for the in-level screen):

File slot	Description
$F0	BG1 tiles
$F1	BG1 tiles
$F2	BG1 tiles
$F3	BG2 tiles
$F4	BG2 tiles
$F5	BG3 tiles
$F6	BG3 tiles
$F7	Sprite tiles
$F8	Sprite tiles
$F9	Sprite tiles
$FA	Sprite tiles
$FB	Sprite tiles
$FC	Sprite tiles

This implies that BG1 tilesets are sets of 3 compressed files, BG2 tilesets are 2 files, BG3 tilesets 2 files, and spritesets 6 files. The specific tileset/spriteset # comes from the level header and what gets loaded into these slots is the compressed file index. There are tables linking tileset/spriteset #'s to the compressed file indices that are loaded in.

BG1 Tileset

The BG1 tileset table begins at $00AF39 and holds 16 entries. There is a completely separate table just for world 6 at $00AF69, but the only tileset # that differs is $01. All BG1 tileset graphics are LC_LZ1 compressed.
