Just to let you guys know, I'd been asking (more like begging) Dave to add graphics for the starbase weapon arcs to the new SFC3 patch we are testing. He came back to me a few days later with a list of new arcs that were added to the game, complete with UI graphics so we can mod them into our ships. Here is the complete list of new arcs that are already in the new patch , as of several weeks ago.
