The God of Thunder Tileset Format is used by God of Thunder to store both tiles and other game images. Since the game runs in VGA mode X (320×240) the image data is split into four planes to match the video memory layout.

File format

The file consists of a number of tiles one after the other. While the format itself is not compressed, it is stored compressed inside the main game .DAT file using the same compression algorithm as all the other unrelated files in the .DAT.


There is no signature, however careful processing of the header can be used to check whether the last tileset ends at exactly the end of the file (allowing for padding in some cases, such as status.) If not, it is unlikely to be in this format.


Each tile begins with the following header.

Data type Name Description
UINT16LE width Width of the image. Multiply by four to get width in pixels.
UINT16LE height Height of the image, in pixels
UINT16LE flag ! Unknown

The image data for the tile follows the header. See Planar VGA for details on the planar layout of the data.


Palette entries 0 (black) and 15 (white) were used during development to help mark out the location of each tile in the tileset. These two palette entries are treated as transparent by the game.
