I made a few changes and compiled and ran it just fine. Double check
everything! Let me know if this doesn't work either.

  ^^^
   I deleted 'MAIN_BMP' and put 0 (zero) in it's place. That way I didn't
need the game.h

Should work now!
Here is what I compiled:

--------------------------------

#include <stdio.h>
#include <stdlib.h>

#include "allegro.h"

//#include "game.h"


main()
{
DATAFILE *data;

allegro_init();
install_keyboard();
install_timer();

data = load_datafile("game.dat");
if(!data){
  allegro_exit();
  printf("datafile not loaded properly\n");
  return -1;
}

set_gfx_mode(GFX_AUTODETECT, 320, 200, 0, 0);

blit(data[0].dat, screen, 0, 0, 0, 0, 320, 200);

while( !keypressed() );

return 0;
}
