Jamyda manages applications that will be launched via the tool DOSBox. The behaviour of DOSBox is controlled by a configuration file that defines, for example, screen resolution and size, sound or periphals like joystick, etc. The main idea of Jamyda is, on the frst hand, to administrate applications and their settings as links on a graphical user interface and to launch them by double-clicking. On the other hand, sets of DOSBox configuration files can be created and reused for every new or exisitng application, created by Jamyda. This simplyfies creating new application enormously.
