Nintendo's Emulator Takedown Sparks Copyright Law Debate.

Nintendo issued a cease and desist warning to Valve against hosting the Dolphin emulator on Steam, citing its belief that it would violate the DMCA. However, Nintendo has taken no action against Dolphin or its developers directly. Emulation advocates believe that emulators themselves are legal, but breaking copyright law is not like making a traffic violation, and there are few hard rules about what is and isn't allowed. The legal situation around emulators remains unclear, and it would be dependent on the decisions of an individual court on a specific instance anyway.
