• 7A00 - 7FFF (0600) = current tileset data (see Tileset Data Format)

Tileset Data Format

Tileset data is decompressed to 67EE - 6D2D (0540), then decoded to 7A00 - 7FFF (0600)

Original format:

• 67EE - 6BED (0400) = tileset - sets of PPU tiles (4 bytes per full tile)
• 6BEE - 6C2D (0040) = tileset - palettes (2 bits per tile)
• 6C2E - 6D2D (0100) = tileset - attributes

Decoded format:

• 7A00 - 7AFF (0100) = tileset - top-left PPU tile
• 7B00 - 7BFF (0100) = tileset - top-right PPU tile
• 7C00 - 7CFF (0100) = tileset - bottom-left PPU tile
• 7D00 - 7DFF (0100) = tileset - bottom-right PPU tile
• 7E00 - 7EFF (0100) = tileset - palette
• 7F00 - 7FFF (0100) = tileset - attribute (see Notes)

Map Data Format

After the tileset data is decoded, the map data is decompressed to 67EE - 74C7 (0CDA) (no decoding necessary)

NOTE: Maps can have 1-16 different screens, and screens can be duplicated in the map screen order

• 67EE - 68C7 (00DA) = header

  • 67EF = map height
  • 67F0 = PPU background banks (see ROM 0x0B428)

  • 67F3 = PPU sprite palettes (see ROM 0x24E65)
  • 67F4 = music
  • 67F5 = background animation delay (00 = off)
  • 67F6 - 68C7 (0010) = map screen order (from top, by rows)
• 68C8 - 6987 (00C0) = map screen 1
• 6988 - 6A47 (00C0) = map screen 2
• 6A48 - 6B07 (00C0) = map screen 3
• 6B08 - 6BC7 (00C0) = map screen 4

• 6EC8 - 6F87 (00C0) = map screen 9
• 6F88 - 7047 (00C0) = map screen 10
• 7048 - 7107 (00C0) = map screen 11
• 7108 - 71C7 (00C0) = map screen 12
• 71C8 - 7287 (00C0) = map screen 13
• 7288 - 7347 (00C0) = map screen 14
