Sorry if I sounded accusatory over the Dune 2 disks - since they had been available before on this board, I presumed you were simply re-uploading someone elses posts. When I mentioned this earlier you simply asked who had previously uploaded them, rather than stating you had imaged them, which made me jump to conclusions. Anyway, my bad.
You are both right about CAPS, there are a fair few AmigaDOS games on that list. I must check out their pages in more detail sometime as I'm wondering if they're actually using the ADF for these originals? I presume so.
