In response to a Twitter user's question about plans to bring Sega games to the Wii U Virtual Console, Yosuke Okunari - a company producer who has worked on 3DS conversions of classics like Outrun and Space Harrier - said plainly that "there are no such plans." Not all hope was dashed however, as Okunari suggested the fan make their desires known to Sega West.
So the bad news is the Wii U Virtual Console shall be sorely lacking Sega favorites like Sonic The Hedgehog, Golden Axe, Altered Beast or - let's face it, everyone's favorite - Vectorman, at least for now. The good news is you can still play most games released for the original Wii's Virtual Console by going through the Wii U's emulation software by selecting the "Wii Menu" channel on the console's start menu. You'll have to use a Wii Remote or Classic controller to play the thing, and you won't have access to that game's Miiverse or off-TV options like you would if it were native to the Wii U Virtual Console, but technically you can still play.
So on the bright side, you're not actually missing out on access to some of these games, it's just time-consuming and inconvenient! Yay?
