Back in the early 80's we would extract video games from cartridges with a memory dump and then transfer that to the old 5 inch floppies. Then upload them to mostly hidden directories in college bbs and internet systems and then share the location in what was then basically chat rooms and BBS boards.

It would take all night to get a game on a 300 baud modem but it did work.

Its amazing how far back network shares really go.
