/**
 * Format specifications for nancy.dat:
 * 4 bytes              Magic string 'NNCY'
 * 1 byte               Major version number
 * 1 byte               Minor version number
 * 2 bytes              Number of games (ignoring multiple languages)
 * 4 bytes per game     File offsets for every game's data
 * 
 * Game data order:
 *      Game constants structure
 *      Array with the order of game languages
 *      Conditional dialogue (logic)
 *      Goodbyes (logic)
 *      Hints (logic)
 *      Conditional dialogue (text)
 *      Goodbyes (text)
 *      Hints (text)  
 *      Telephone ringing text
 *      Item names
 *      Event flag names
 * 
 * Arrays in the game data are variable-size.
 * All arrays are preceded by a 2-byte size property.
 * 2D arrays with strings (e.g conditional dialogue) are also preceded
 * by a list of 4-byte offsets (one per language).
 * Nonexistent data isn't skipped, but has size 0.
 * All offsets are absolute (relative to start of file)
 * 
 * Game order:
 *      The Vampire Diaries
 *      Nancy Drew: Secrets Can Kill
