These settings allow you to manage config-files (which have the extension .uae). These config-files have both a name and description, and control the behaviour of WinUAE. Basically, a config-file is an encapsulation of the settings found on all the other pages in the GUI.
Loading a Configuration:
You can load a configuration by selecting it from the list and then clicking the Load button, or by double-clicking a configuration in the list.
Additionally, you can double-click any .uae config-file from the Windows Explorer, or from a Desktop Shortcut. The configuration will load, and if the Show GUI on Startup setting is disabled, WinUAE will immediately launch into emulation-mode, bypassing the GUI completely.
Saving a Configuration:
To save your changes for a configuration which you've loaded, simply press the Save button. If you've made changes to a configuration and want to save it under a different name, simply change the Name field on this page of the GUI. You can also adjust the Description field.
Deleteing a Configuration:
Select a configuration from the list, and click the Delete button.
