@Thomas Richter
Can you please explain to me what market you keep talking about?
There is no such thing in terms of AmigaOS3.9, I mean at all. I guess there will nobody ever fix or improve OS3.9 due copyright issues and other problems.
Basically nobody cares about development of OS3.x, not even Cloanto, even though they are offering updated Kickstart and slightly modified original AmigaOS3.1. Which is great as replacement disks or for emulators, but nothing more.
