Dapplegrey v4.2.4 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.

Important hints for users of earlier versions:
- Disk images added to the drives won't be imported from the games list of earlier Dapplegrey versions properly. Sorry, you have to re-assign disk image mountings once before running a DOS game again
- Since there is an un-resolved problem with assigning multiple number of images to a drive, it is recommended to organize the Floppy & CD images within folders per game. When attempting to add multiple Floppy & CD-ROM images to a game entry, open the dialog 'Drives', select 'Disk Images'. Then, simply browse to the folder containing the desired disc images. Dapplegrey will let DOSBox mount all the disc images stored in this folder.
- If you're using Mac OS X 10.8 Mt. Lion as Operating system, you may have to hold down the 'alt' key before starting Dapplegrey the very first time.

Dapplegrey v4.2.4 Changelog:
Finds more *.ICO files than 4.2.3, but again, this takes effect for the first time in Dapplegrey 5 later this year.
When adding games, the „Drive C:“ Folder selection dialog now starts with the last selected folder by default, instead of the documents folder used before.
Also changed in the Add Games window, the default setting of browsing to a game by folder or by DOS application is now set to folder. This has been changed because of Mavericks which needs a while to display the content of a folder. Now, just browse to the folder and you’re done. After adding a game, set the DOS application you want to run the game with, by using the „Drive C:“ settings dialog.
