>>22739417because you have to reverse engineer the processor, 3DS runs fast because all of its hardware is dedicated to it, a lot of emulators run shitty on pc's etc because you can only donate a certain amount of resources to it
there will most likely never be a 3DS emulator and if there ever is it will not be for at least 7 or 8 years, there still isn't even an original xbox emulator that runs well yet, and that was released in 2003
its a very complicated process, the more advanced consoles get the harder it is to make things that can emulate them, we just got around to being able to emulate the original ds/dsi, imagine how long it will take to emulate the 3DS?
