if you enjoy hoarding stuff like this then it's worth it. 8GB of space for such a massive archive is really not that much, so it's not like it is costing you anything to archive them.

If you don't want to hold on to these files for whatever reason, upload them somewhere such as archive.org then other people can hoard them if they choose to do so. I bet there is something in there that someone has been looking for, and I guess that's what hoarding data is all about, making sure that media, in this case games, don't get lost to time like many have.

I have never heard of that manufacturer.
