      feature is needed by an HuC-3 game

    * The SDL frontend now has the ability change the default window size

  Bug Fixes

    * Fixed a bug that caused the Quick Look previews to include a border on

    * Fixed a bug where the RTC might drift when loading older saves or
      states, or when pausing SameBoy for a long time
