Dapplegrey v2.16 is released. Dapplegrey is a frontend for the MacOS X DOSBox port (which you can get from the official DOSBox website) written in REALbasic. Not only the plain DOSBox app, but DOSBox versions included in DBGL or Boxer will also be recognized as DOSBox binary source. With Dapplegrey you can easily set options the DOSBox gives to you w/o having to enter them manually using the Terminal or have to edit the DOSBox config file. This file will be written before Dapplegrey tells DOSBox to start the DOS game.

Dapplegrey v2.16 Changelog:
* When switching between game entries: no longer force quit, if the DOS application previously selected can´t be found (for example, if the host drive where the DOS app is stored, isn´t mounted to the Mac Finder).
* When the DOS application previously selected can´t be found, the toolbar button ´DOSBox´ will be disabled (finally). Usually, if you click this button, the game will be started.
* The popup menu (see pict below) introduced in version 2.15 works now with Dapplegrey´s own toolbox entries, too.
