Actually, Nintendo took out a patent on emulation of Nintendo systems and games on other devices, so Nokia could very well be facing a lawsuit for allowing these to be made available officially. Whilst I don't agree with it, those of you taking the "backup copy" defence you would still be in trouble as copyright does not allow it without specific permission from the copyright holder, i.e. you're not going to get it.

Most countries have never had "fair use" mandated in their copyright laws, though in practise it's usually overlooked; the one country that I believe used to have it was actually the USA, which allowed TV recordings to be swapped on VHS, etc, however that pesky loophole was closed by the Digital Millenium Copyright Act (DMCA).
