Until machines reach end of life and break, and nintendo won't offer any official way of playing the games that people own - because of course they won't. We already know they don't even allow savegame backups without a BS subscription fee.

Emulation and piracy are very important ways of keeping a historical record of digital works that otherwise would vanish. We have countless examples of abandonware being kept alive by piracy.

Also I'm considering jailbreaking my wii because the games I bought - including one just a couple of weeks ago - are becoming impossible to play because the discs just don't last. I've had to clean this second hand one off many times to keep playing it. It's piracy, sure, but without it the entire catalogue would just vanish. If nintendo had their way the only way to keep those games would be to pay them a subscription for the rest of time.
