I believe CAPS is interested in preserving all Amiga games, protected or otherwise, since that is the initial concept (keeping the original games from extinction). For sure the protected disks get more publicity, due to the controversy of whether this process is even possible, etc. So that bit rises to the top, but the organization is interested in all originals.
Marz, let me repeat again, absolutely *NO* downloaded 'originals' should be contributed. Doing so will only add to your questionable reputation. If it is not a store bought, absolute original copy with no modifications of any kind, don't even consider it. Please!
