Nintendo and Microsoft arent in this case

So...are you saying I can play my SNES/N64 cartridges and my gamecube's discs on my WiiU?

Or my GBC/GBA cartridges on my 3DS?

Because if you can, please tell me how.

every PS3 can play every PS1 disc, here you have your answer if you want to cross between 2 generation. Why should nintendo put multiple cartridge slots into their system. We are talking about Discs here, stop damage controlling these companies
