Also, as much as some may hate to admit it, we have to remember this:

Due to this, a post on LoveROMS' Facebook page has a point:

Virtual Console wouldn't have been possible without preserving ROMs on the internet, so Nintendo should be thankful for the ROM sites hosting ROMs, because preserving video games is important for historical purposes and for availability. Even though it is within a copyright holder's legal right to take court action, copyright holders should never really bully or request removal of games that have been available for more than 3 years, otherwise some games may end up being lost in history and never seen again.

The Wii Virtual Console will be no more after January 2019. Many of the titles available for download have made their way to the Wii U VC, yet there are many more which did not. (And the Wii U VC will eventually be no more, either.)

For example, Monster World 4 got a special localization for the VC for it's first time release outside Japan. The only way that new players will ever be able to play that localized version of the game, without having purchased it before the service is ended, will be to download it's ROM files off the internet.

Without a legal avenue of access by Nintendo, there will be no other choice. In cases such as this, it is justified to have them be available online for the sake of historical preservation. Otherwise, the localized version of Monster World 4 would eventually be lost forever to the sands of time.

Meanwhile, Nintendo STILL has given no solid indication whatsoever that they will reintroduce the VC as we know it to the Switch. Take heed- there's only a little more than 5 months left. Then the largest official digital repository of Nintendo's (and possibly also for NEC's TG-16/PC-Engine) home console backlog will no longer be widely available to the general public...

According to Wikipedia:

As of January 26, 2017, there are 398 titles for NA Wii VC, and only 267 titles for NA Wii U VC. As of December 8, 2016, there are 385 titles in EU and 384 titles in Australia and New Zealand for the Wii, and only 258 titles for the EU/AU/NZ Wii U VC. Meanwhile, there are currently 659 titles for Japanese Wii VC, and only 466 titles available for the JP Wii U VC.
