So the solution for Nintendo would be to take a risk and make their own encryption scheme? That way just trying to support that prorietary encryption scheme in the emulator would be enough to run afoul of the DMCA. But then, as a workaround I could see the proprietary encryption code being supported as an addon (ie: DLL file) that you can just drop in, without distributing it with the emulator itself and letting the users search for it on the digital high seas.
