ICO Format (Halloween Harry)
alien.ico/harry.ico (and others inside the .bnk files) are tilesets containing the graphics for Halloween Harry/Alien Carnage. They consist of a number of consecutive image chunks composed mostly of raw data.
There is no palette stored in the ICO file. The data is merely palette indices prefixed by a two word header giving the image chunk's dimensions. It is possible to determine the number of chunks by reading through the ICO file.
|UINT16LE||width||Width of image|
|UINT16LE||height||Height of image|
|BYTE[width * height]||data||Pixel data (8bpp)|
