MIM File structure

The MIM filestructure begins with the

MIM Header

typedef struct 
{
   UINT32   Header_Palette;
   UINT16   PalX, PalY;
   UINT16   PalWidth;
   UINT16   PalHeight;
} MIMHeader;

which is followed by PalHeight number of

MIM Palette

typedef struct
{
   UINT16   Palette[256];
} BGRPal256;

After the palettes comes the

MIM Block Header

typedef struct
{
   UINT32   WordCount;      // # words of data in image
   UINT16   ImageX, ImageY; // location of blocks on 1024x512 display area
   UINT16   Width, Height;  // Width is the # of Word units (UINT16) the blocks are wide
} MIMBaseImage;

lastly the actual block data for display follows. The palettes are selected from information in the DAT section 3 data.
