 Leaderboards:
 By default the emulator assumes all leaderboards queried by the game (FindLeaderboard()) exist and creates them with the most common options (sort method descending, display type numeric)
 In some games this default behavior doesn't work and so you may need to tweak which leaderboards the game sees.

 Build id:
 Add a steam_settings\build_id.txt with the build id if the game doesn't show the correct build id and you want the emu to give it the correct one.
