MOBY Extras Manager
How to reach it
In Games & Emulation Main Screen open the context menu of the image viewer (top right corner, right click) and choose the Open MOBY Extras Manager menu item.
How it works
Here you can manage extras from mobygames.com (screnshots, cover-art etc.).
Entries in italic font are currently not downloaded images. Entries in normal font are already downloaded.
Use the Move Up and Move Down buttons to re-order the images.
Untick the checkboxes to decide that they won't be shown in the Games & Emulation Main Screen.
Tick the Download extras when selected option and Metropolis Launcher will download any extra you select in the MOBY Extras Manager.
