Nero InfoTool said that CS0G date is 4. February 2005, and on LiteOn site thay say that it is 4. March 2005.
I think there is a difference between timestamp in firmware and public release date. The date on the website is the first day it was available there. BS0S on the website says 24-12-2004, but in the firmware it is 14-12-2004. In VS0G (832) the timestamp is 17-12-2004, but was available much later on the website, 04-02-2005.
