Dapplegrey v2.15 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 v2.15 Changelog:
# In previous versions after adding a game entry you were fixed to the DOS executable file once set for a game entry.
Yes, you could choose a DOS executable file again with the 'Browse' button located near the text field listing the path to the DOS executable file, but now Dapplegrey looks for other DOS executable files in the folder set as drive C:. Dapplegrey will list all these files in a Popup
menu located in 'Game Files' tabulator panel, where you can select the
desired DOS executable file you want to run the game entry with.
# As DOSBox source also recognizing the "Mac OS X DOSBox game wrapper with 3Dfx Glide support", which can be found in the VOGONS DOSBox forums.
