Ok so are you saying I should delete my rom collections that I've had for about 10 years because of the Virtual Console that came out 2-3 years ago? They are just cashing in on emulation. Something that was looked down upon by them since it started. Stop feeding big corporations while they milk everything they've made for it's last penny.
That ROM collection that you've had for 10 years was illegal 10 years ago. IF
you want to follow the law, you should not have that ROM collection. There is an exception to those ROMS which you own a physical copy for, depending on the country where you live.
If you had a ROM of a game 10 years ago without owning the real thing (even then, it depends on your local copyright laws), then it was just as illegal 10 years ago as it was when Nintendo started the Virtual Console.
Downloading ROMS you do not own has ALWAYS been illegal, whether it is available to buy on something like the VC or not. Is it morally wrong to download a game that is unavailable on digital download systems that you can only find on eBay (where the company that made it would see no royalties from your purchase)? That is for you to decide.
