Well it's a good thing I downloaded it years ago, but still, removing games without even a hint of it being taken down is a real dick move. This is the same thing they did with the Donkey Kong Country games which still pisses me off because I was planning on downloading DKC3 but it got removed without warning so I wasn't able to.
At least when they were going to remove Irem's R-Type games we got a warning which is why I went and downloaded R-Type for the Turbographix and R-Type 3 for the SNES right before the day they were removed. But this and Donkey Kong are just bullshit.
I guess the lesson here is if there's any games left on the Virtual Console that you haven't downloaded yet, better get them now since they can be gone without warning. And considering how slow the Wii U eshop releases are, better get them now because who knows how many years it'll take for them to appear on that system.
