title: Binary file & saved game formatting
body: <p>I am working on a small roguelike game, and need some help with creating save games.  I have tried several ways of saving games, but the load always fails, because I am not exactly sure what is a good way to mark the beginning of different sections for the player, entities, and the map.</p>
  
  <p>What would be a good way of marking the beginning of each section, so that the data can read back reliably without knowing the length of each section? </p>
  
  <p>Edit: The language is C++. It looks like a readable format would be a better shot.  Thanks for all the quick replies.</p>
