+===== Tile Sets Data =====
+Each tile set is $800 and has a maximum of $100 tile (16x16). Each tile is composed of 4 8x8 subtiles, top-left (1), top-right (2), bottom-left (3) and bottom-right (4). Bytes $400 to $7FF are one byte of data per subtile, starting from all top-left subtiles ($400-$4FF) and following same order as described above. As an example consider tile $F3 of the tile set:
+|  subtile  |  tile set offset  |
+|  top-left  |  $4F3  |
+|  top-right  |  $5F3  |
+|  bottom-left  |  $6F3  |
+|  bottom-right  |  $7F3  |
+This data byte has the following format:
+|  bit 0  |  ?  |
+|  bit 1  |  ?  |
+|  bits 2-4  |  Palette ID (0 to 7)  |
+|  bit 5  |  Priority one  |
+|  bit 6  |  Mirrored  |
+|  bit 7  |  Inverted  |
