Tiles are blocks of art that are displayed on the screen.

8x8 tiles

8x8 tiles consist of 64 pixels. All the pixels in one 8x8 tile must use the same palette line.

16x16 tiles

16x16 tiles are mappings of 8x8 tiles. The properties of 16x16 tiles include:

  • The palette row for each tile it contains.
  • The plane for each tile it contains.
  • The drawing mode (normal, backward, upside-down, both) for each tile it contains.
  • The collision index for the whole tile.

96x96 (Sonic Advance 1/2/3), 128x128 (Sonic 2/3/&K), 256x256 (Sonic 1) tiles

These are mappings of 16x16 tiles. The properties of these tiles include:

  • The solidity (not, top, all, left/right solid) for each tile it contains.
  • The orientation for each 16x16 tile it contains (normal, backward, upside-down, both).
