I've heard countless arguments about this topic, and wanted to start a conversation about this. It's been 3 updates so far, and Sky is still working. So it basically emulates, down to the smallest detail, a real retail cartridge. It does not depend on an exploit, and so it hasn't been blocked. I've heard that, because it is unblockable, All Nintendo can do is ban consoles using the included headers in the template. Is it really unblockable?
