Instead of users downloading the large 'Gamebox' files that contain DBM tilesets for Cyberboard, it may be a better idea to just download the empty gamebox and then to download the actual 'Game Library Tile Files' (GTL files) that are required. People like Charlie Zwinnak are producing really beautiful pieces of artwork that really enhance the game.
I have attached here a link to a GTL set for the Neo-Babylonians that I have created. The others were created by Charlie Zwinak, and the French Ordonnance by another gentleman whose name I have to find. Click on the link to download the zipped files:
To use the files, when in Cyberboard Designer, double click on Tile Image Sets, to create a new set of images, enter a name for the set, then go to 'Project' on the menu bar, and select 'Load Tile Image Library'.
