The main benefit of using Dapplegrey for DOSBox is that it allows you to change the settings of the emulator without having to use the command line or edit DOSBox files manually.
Although you can use Dapplegrey for any kind of application, it's specially focused on video games. It even shows a list of all the games available on the computer.
Dapplegrey lets you visually configure different parameters in DOSBox, such as the memory, CPU, screen, network, sound, units, and more.
For Mac OS X 10.3 or higher. Requires DosBOX.
