Yeah, I've seen such statements many times and looks like redump, SPS don't even think to give as all dumps. In fact redump does not even have any dump. TOSEC is exception but they sorting mostly stuff that is already public (except TOSEC ISO - the only case then all material was shared).
Better keep faith in contributors rather project coordinators.
Now, please, more people coming
List updated. Now it should have only amiga games (except dual editions naturally).
