Backwards compatibility on 3DS and WiiU?

DS games run fine on 3DS, but apparently there's colour issues. Far as Wii U is concerned, they stripped out Gamecube BC for no reason. Wii games run.

They took out Gamecube BC on the Wii too, I believe it happened around 2010 when colors started appearing. It was and is to save money as a slot loader is much easier (cheaper) to make that only accepts 1 size disc instead of two. I still have my Wii if I want to play the 3 Gamecube games I still have (ie. didn't get rid of) but with Wind Waker getting an HD remake I'll be down to two :) (hoping Wii U's VC eliminates those as well). The only thing I don't like about Wii U's BC is you have to load the Wii Menu app, which really just restarts the Wii U into the older Wii's OS and from there you are literally playing a Wii, 3DS's BC is better, you can pop in a DS cart and run it just like you would a 3DS cart and if you imported stuff from your DSi like I did it runs the same as stuff you downloaded on your 3DS, pretty seemless and more than I would expect from Nintendo, the Wii U BC is closer to what I would expect but still wish it was more seemless.

How much money could they possibly be saving?  I still never understood Nintendo's problem here though.  Even the WIi had to restart to load GC games, which is stupid, they're both the same architecture.  It's like me having to restart my computer everytime I wanted to play Quake.
