MatthiasM Posted June 8, 2008 Report Share Posted June 8, 2008 There already is the dormant http://libnetmd.sourceforge.net/ that still requires a lot of work to get the specification of Sony's proprietary, encrypted and restricted NetMD-interface by reverse engineering. But if it could be done, we would have a working multi-platform alternative to Sonys disfunctional and user-restricting software.But this is not an easy task, as it requires an reverse-engineering-expert, who might need some time until everything works sufficient and it sounds like a quite frustrating job, so there has to be some financial reward.The plan "collaborately fund Open Source": many users bid money for a developer to take the task. The people who bid more money, get more influence on the development. If the jobs nears completion, the users test and give their okay: the money gets transfered to the developer.http://www.cofundos.org/project.php?id=122 Quote Link to comment Share on other sites More sharing options...
kino170878 Posted June 8, 2008 Report Share Posted June 8, 2008 I don't think it needs a large sum of money really. Some guy has supposedly already reverse engineered the Atrac3plus codec and nearly achieved full unrestricted access of Sony's OpenMG platform. The NetMD stuff I think would be similar, so it should definately be possible. Quote Link to comment Share on other sites More sharing options...
Strungup Posted June 8, 2008 Report Share Posted June 8, 2008 With the nature of Sony"s vehemence , Openly posting the idea of reverse engineering their proprietary software , whether defunct or not , I dont think is a very good idea . There are Sony people who browse the boards , unknown to you . Sony's R&D dept , is on 24 hour search and find , to determine trends and figure out was WILL be popular . ( Even though they get it wrong half the time ) Quote Link to comment Share on other sites More sharing options...
marcnet Posted June 10, 2008 Report Share Posted June 10, 2008 (edited) Some guy has supposedly already reverse engineered the Atrac3plus codec [/quoteTrue. I chatted to him online. He is still at university or college, so he dosnt want to risk his future career by giving away Sony secrets. He wouldn't tell me how to decrypt OMA/OMG files although he claims to of done this himself. A few things he hinted at:* The encryption is DES based (3DES or some other DES, I do not know)* Sony put in a lot of effort to keep hackers / reverse engineers away. Such tactics include self-generation of code upon executing, false code and disabling any running debuggers.I am not an encryption guru myself though I have done my share of reverse engineering over the years. Unfortunatly I am busy on other projects and am less inclinded to contribute on this project since I heavally work with computers in my job and need a break in the evenings/weekends However, I can still offer any advise if neededGood luck with the project Edited June 10, 2008 by marcnet Quote Link to comment Share on other sites More sharing options...
MatthiasM Posted December 13, 2008 Author Report Share Posted December 13, 2008 There is an offer by a software developer: http://cofundos.org/project.php?id=122 Quote Link to comment Share on other sites More sharing options...
cbmuser Posted April 10, 2009 Report Share Posted April 10, 2009 There is an offer by a software developer: http://cofundos.org/project.php?id=122We have also made alot of progress already:https://wiki.physik.fu-berlin.de/linux-minidisc/We're already able to decode MP3s off HiMDs, those are not 3DES-encrypted, just a simple XOR-encryption over the MDs DiscID.Adrian Quote Link to comment Share on other sites More sharing options...
