Uh huh, yeah, Throw a A8 on a flashcart (or even a lesser chip) or some intel equivalent onto a that size of PCB, and cool it? It's not just a power supply problem, its a size problem. If you think in three years, that we can fit hardware that can emulate a GameCube (most games at full speed, I'm not even gonna talk about some of the more intense games), let alone a Wii, onto a fPGA flashcart, and have enough power to keep it running, and not exploding from the heat, and keep it going for more than minutes (over an hour), then your dilutional. Even the Android version of Dolphin that's in development right now can't achieve more than a few FPS because smartphones don't even have the sophisticated opengl libraries that x86 machines (this will however be alleviated quite a bit when Tegra 4 comes out according to the devs. However, to do anything really worth while, ARM is gonna have to get a lot better, and those technologies will either be too expensive to put on something as small as a Flashcart (if the 3DS is even hacked by then, mind you) or practically impossible.
This post is directed at anyone who thinks that having a cart like the DSTwo for the 3DS can achieve GC emulation, not just you Ziver.
I don't think it's out, but I'll check. One major reason that its THAT SLOW is that it is currently relying on a software renderer, and chips like the Tegra 4 will have newer and better OpenGL ES libraries to get a good renderer going. However, you'll still need good amount of CPU horse power to do anything with that renderer blackens.
