Kaytrim.... To qualify what I write here... I'm not a Lawyer, but I am trained in UK, EU, and US Copyright Law.
You are all pretty much, so far, missinterpreting this ruling by being extremely selective about what you are reading in it. You have missed several very critical points!
1) This ruling DOES NOT grant rights to Circumvent Copyright. It is only about the control of access via obsolete copy protection methods. It is NOT about freedom of, or exemption to Copyright in the material itself.
2) This ruling ONLY grants rights to circumvent obsolete protection schemes, in doing so it does NOT make the Copyright obsolete...and it only grants the rights under very specific circumstances as follows:
a) You musty be a library or formally recognised archive or educational institution.
Pretty much non of us are a Library or Archive or Educational institution under the recognised Legal Definition.
b) You must ONLY make non infringing use of the material and that use must be Archival, or under the terms of the ruling for very specified educational use.
Copying of ROM's IS NOT non infringing use of the material, distributing ROM's is most certainly NOT non infringing use of the material. Copying ROM's in order to play games is NOT non infringing use of the material, nor is it for the purpose of education as strictly specified in the ruling.
c) The copy and use STILL must not be in breach of the DMCA.
The DMCA is very specific... That is where you will find the terms and conditions for the actual application of copyright in the USA.
This ruling DOES NOT in any way alter the copyright in the material or deminish in any way the rights of the owners and licencees of the original work.
It is therefore of very little use to us whatsoever and does not really apply to us. Because as a legal document, you CAN NOT, read parts of the ruling in isolation and ignore the parts you don't like. They all form part of the ruling itself.
I did answer much of this in the two other threads that started on it. See:
http://forum.arcadecontrols.com/index.php?topic=60599.0Additionally.... This ruling DOES NOT protect Mame OR the Mame Devs or the guys who do the ROM dumping to add to the Mame Archive, because that very same Mame Archive is then distributed by the guys doing the ROM Dumping and that then means that they fall under the terms of the "non infringing use" clause..... That is to say that what they do by giving the dumped ROMs to someone else, is then NOT a non infringing use.
