The Wii and Wii U have plenty of controllers and combinations on offer, even if on most occasions we can instinctively pick up our pad of choice and get on with playing. With the Wii U and Wii Virtual Consoles, though, there can be quirks that trip people up, one being the fact that the Wii U GameCube Controller Adapter works in Super Smash Bros. for Wii U but not in Wii games - or any other games, for that matter - that supported the controller on the last-gen hardware.
That GameCube controller example with the Wii U is probably the trickiest example, but in any case a keen retro gamer over on NeoGaf has decided to pull together an infographic to show which controllers work with each platform across the existing Virtual Console platforms. Most of it is fairly obvious, though there are some examples that can always use some clarification.
You can see it below, and overall it's a pretty handy table; be sure to check the notes at the end to explain some of the symbols seen throughout.
You can hit up the link below to see a larger version of the image, and if anything this is a reminder that Wii and Wii U gamers need to keep a fair variety of controllers to hand if they're jumping between retro games.
Thanks to Ryan Millar for the heads up.
