If you own a nintendo game and a cartridge, make a rom of it, and then play that rom on a more lifestyle compatible system then it shouldn't be a big deal.

I think the copyright on video games should end at 7 years, maybe 10 at the worst. You have a decade from the date of publication to make your money on that version of the game. What percentage of games are profitable 10 years after publication? I know there are a few, minecraft, WOW, Skyrim, COD, but even if there are 500 games on the 10+ list, that pales in comparison to the number of games that come out every year.

I bet most 7-10 year old games are lost to history, if you include ALL video games and not just the breakout hits and AAA best sellers.
