The Captain Comic Tileset Format stores the images used for drawing the game levels. All tiles are fixed as 16×16 pixels in size. The format is very similar to the Captain Comic Sprite Format.

File format

Data type Name Description
UINT8 lastPassable index of last non-blocking tile, tiles of a higher index block the player (walls, ledges, etc.)
UINT8 unknown1 ! Unknown - always 0x00
UINT8 unknown2 ! Unknown - always 0x00
UINT8 flags 0=default, 4=unknown, only used in CASTLE.TT2

The tile data follows this header, in blocks of 128 bytes per tile.

The tiles are 16-colour images, split into four planes (see Raw_EGA_data#Planar_EGA_data). Each image is stored one after the other (no header.) The planes within each image are ordered with blue first, followed by green, red and intensity last. 32 bytes per plane multipled by four planes gives 128 bytes per tile.

As each image is entirely contained within the 128 bytes, the offset of a given tile can be calculated as

offset = 4 + tile * 128

The filenames for each tileset match the levels, so FOREST.TT2 contains the tiles for the three map files FOREST[0-2].PT.
