From Wikipedia:
http://en.wikipedia.org/wiki/Console_emulator#Legal_issuesLegal issuesAs computers continued to advance and emulator developers grew more skilled in their work, the length of time between the commercial release of a console and its successful emulation began to shrink. Many fifth generation consoles such as the Nintendo 64, the Sony PlayStation, and sixth generation handhelds, such as the Game Boy Advance, saw significant work done toward emulation while still very much in production. This has led to a more concerted effort by console manufacturers to crack down on unofficial emulation. Because the process of reverse engineering is protected in U.S. law, the brunt of this attack has been borne by websites that host ROMs and ISO images. Many such sites have been shut down under the threat of legal action. Alongside of the threat, link rot has occurred at several links without update to the webpages.
Another legal consideration is that many emulators of fifth generation and newer consoles require a dumped copy of the original machine's BIOS in order to function. As this software is protected by copyright law and typically not accessible without specialised hardware, obtaining them generally requires the user to obtain the file illegally.Basically supports what I said earlier. Emulation is not illegal but the BIOS (if any) falls under copyright law, as does the program data (ROM).

More information, from
Nintendo's own current website:
http://www.nintendo.com/corp/legal.jspNote how they consistently refer to "
illegally copied Nintendo software" and at no point in the entire page do they state that emulator programs are in themselves illegal. They do claim that copying devices (hardware) are illegal (which is debatable). And they state that they feel emulators promote piracy and hurt their business. However neither of these positions makes an emulator illegal. They could perhaps take an emulator author to court based on that position (damages to business, revenue, trademarks, etc) but that still doesn't make the emulator itself "illegal".

More, from Wikipedia's page on emulators in general:
http://en.wikipedia.org/wiki/EmulatorEmulators in computer science
Emulation refers to the ability of a program or device to imitate another program or device. Many printers, for example, are designed to emulate Hewlett-Packard LaserJet printers because so much software is written for HP printers. By emulating an HP printer, a printer can work with any software written for a real HP printer. Emulation "tricks" the software into believing that a device is really some other device.I'd like to find information on any cases involving HP suing other manufacturers for using these "printer emulators". All I could find was lawsuits against third-party ink cartridge makers.

Here's Wikipedia info about reverse engineering:
http://en.wikipedia.org/wiki/Reverse_engineeringReverse engineering(2nd paragraph)
In the United States and many other countries, even if an artifact or process is protected by trade secrets, reverse-engineering the artifact or process is often lawful as long as it is obtained legitimately.-----------------------------------------------------------------
DMCA - ExemptionsThe main purpose of the DMCA was to include digital media under copyright laws and also include laws against circumvention of "DRM". However there are
exceptions to the rule:
Lot's of citations online... pick your prefered one, but the main
exemption applicable here is (as of 2006):
2. Computer programs and video games distributed in formats that have become obsolete and that require the original media or hardware as a condition of access, when circumvention is accomplished for the purpose of preservation or archival reproduction of published digital works by a library or archive. A format shall be considered obsolete if the machine or system necessary to render perceptible a work stored in that format is no longer manufactured or is no longer reasonably available in the commercial marketplace.Exactly on target for what we're discussing here, although almost a moot point considering that the DMCA is applicable to the USA only.

Familiar with
Sony VS Connectix? More interesting than that single case is the fact that the company's business was almost entirely based on emulation for commercial profit. They made Virtual PC for the Mac as well as the Playstation emulator. Founded in 1988 they didn't close doors until 2003. If you read up on their history
HERE you see that Sony ended up having to BUY OUT the rights to the emulator in order to stop it as the courts would not rule in Sony's favor. Microsoft BOUGHT the rights to Virtual PC (and continues to market it). If these things were so obviously "illegal", Sony would not have had to resort to a buy-out, and Microsoft would have been able to sue or bully the company into surrendering the software.
-----------------------------------------------------------------
In conclusion...........
I don't know how emulation skirts patent issues. But I hope all this information settles the argument.
An emulator is kind of like a bong. Perfectly legal to buy one in most places, but the content you use it for is not.
