Why owning a cartridge mattered in court
Nintendo could control how its games were copied, but that did not automatically let it control what a store did with a legitimate copy after buying it. Under the first-sale rule, the buyer of a copyrighted copy can generally lend or resell that particular copy. Renting a cartridge was treated as lending the purchased object—not making a new copy of the game.
That distinction left Nintendo with a harder case than simply arguing that games were copyrighted. To stop rentals outright, it needed a legal basis for controlling the cartridge’s next use. Copyright law gave it stronger control over reproduction than over the circulation of copies already sold.
The fight narrowed to copying
Nintendo challenged the rental business and also objected to practices such as photocopying game instruction booklets. That raised a different issue: reproducing a copyrighted manual is not the same as renting the original cartridge. A rental shop could potentially infringe copyright by making unauthorized copies even when renting its purchased games was allowed.
The distinction mattered because it kept the dispute from becoming a blanket ban on game rentals. Nintendo’s effort to use copyright law to shut down the practice did not succeed, and stores continued renting games.
The tradeoff for players
Rental made games cheaper to try than buying each one, while giving Nintendo less control over how often a single cartridge changed hands. For players, the practical limit was the number of copies a shop owned: a popular release could be checked out before the weekend began. That familiar Friday-night scramble was the market’s answer to a legal right Nintendo could not simply erase.**
