The best chance something like Wario Land has, is to distance itself from the Virtual Boy if it were to be rereleased.
Port and colorize it and position it as a 3D Classic, with no mention of its Virtual Boy roots. And satisfy the fans that are aware of its nature with a setting that can be triggered for original graphics.
I feel like my response earlier in this thread was pretty much right on the mark. To sum up the basic points, it goes pretty much like this.
1. Poor reputation
2. Too expensive to port
3. Too expensive to emulate
But it all goes back to the Virtual Boy's reputation, much of it unfairly earned, as a miserable failure. Sadly, that's not reflective of reality since Nintendo surely knew this was a risky proposition. So that it failed wasn't exactly a shock and shouldn't be held against it to the degree that it has been. I'd say that the Wii U is far worse of a failure with expectations like selling 10 million units alone in 2013, a figure that only now has been reached. They half expected this result with the Virtual Boy, but the Wii U was supposed to be a hit coming off the Wii with its 100 million units sold.
Despite its commercial performance, those that have actually played this and given it a chance have realized that the Virtual Boy has several good games. But much like E.T., too many that know little to nothing about this have been spreading how big of a disaster this was for too many years. That makes it a difficult proposition to justify the expenditure to make some of this material available again.
It's the absence of their early 80's arcade library that is the much more puzzling of the two, and is more deserving of complaints from folks like ourselves. Easy to excuse this, but difficult to justify something like Mario Bros. not being available in arcade form on modern Nintendo platforms.
