  Below is a table to help in the identification of C64  bitmap  files.  If
you require further information about how bitmaps are  displayed  then  you
should refer to the C64 Programmers Reference Manual.

  To automatically identify the type of  file,  you  need  to  compare  the
length of the file and the Load address. Once you have identified the  file
type, you can then use the bitmap, screen and colour offsets to help in the
displaying of the bitmap.

Format for file types:
       Load   - Load address (first two bytes of the file)
       Length - File length in bytes (including load address bytes)
       Bitmap - Bitmap offset (8000 bytes)
       Screen - Screen data offset (1000 bytes)
       Colour - Colour data offset (1000 bytes)
       ScrCol - Screen colour offset (1 byte)
