Thank you for the answer. It may be good to put these links on website (maybe FAQ section). Who knows, maybe it will attract developers in future (like it happens for ReactOS for example).

Where are source codes?

Don't quite understand what do you mean. Users of old OSes are already having problems with absense of security updates. Adding closed source hacks makes this problem only worse. Maybe you are talking about making patches open source only when they are completely ready?
