Are there adapters to use one controller (possibly Xbox) as both Wii classic controller and as Gamecube controller? [closed]

Basically I want to have one single gamepad (and I like the Xbox layout best, but it's not imperative), so I am searching for one of the following solutions:

• One or two adapters USB (at least Xbox compatible) -> GC & Wii Classic Controller
• One adapter GC -> Wii CC or vice versa

Solution 1:

YES, there is an adapter, the Classic Linker from EMS (also in the Plus and N64 variants) that allows you to connect the Wii Classic Controller as a Gamecube controller, allowing you to play gamecube games with a Classic Controller. (You might want to get the N64 variant, as according to the documentation, the other two have weird button layouts.)
