HELP !!??
I'm programming a very nice game with DJGPP and allegro. I use SVGA
640*480*256 colors, so graphic looks good. But the problem is the
double buffering. It's just too slow. Example :

  BITMAP *buffer = create_bitmap(640, 480);

  clear(buffer);
  while( game_continues) {
    // some drawwing on the buffer
    blit(buffer, screen, 0, 0, 0, 0, 640, 480);
  }

That is a the only way I can think of, but itsn't fast enough.
So is there any faster way to do that 'blit(buffer, screen, ...)' ???
