Of course it is legal to write an emulator for an existing hardware. No
one can stop you as long as you do not break patents - which is very
unlikely if you emulate hardware in software and do not clone the
hardware in hardware.

Another question is if you are allowed to run AmigaOS 4 on this
emulator. Of course it is not allowed to copy AmigaOS 4. You must try to
buy AmigaOS 4 and this may be difficult (but is possible if older
hardware breaks and one may buy AmigaOS 4 on ebay then). Licenses like
"you are only allowed to run this software on certain hardware" are
valid in some countries and have no consequences in others. I don't know
if AmigaOS 4 has a license type of this kind and of course one should
check this before we start such a project.

I don't know if the copyright holders of AmigaOS 4 will be happy with
this project or not. Especially because I do not know who the copyrights
holds at the moment. If this is a problem I will try to solve later.
AFAIK I am (legally) allowed to run AmigaOS 4 on an emulator if I own a
legal copy of AmigaOS 4 and do not run this copy on another computer at
the same time. This is true for Windows, MacOS X and all other software
in Germany.

Of course this is off topic. That's the reason why I added "OffTopic" in
the title of my mail. But I have to start at one place to evaluate if
there is any interest on such a project. And I don't know any better
place than this mailing list. If some people say there are interested
and want to help I will open an extra mailing list where we will
discuss. In the meantime I would like to continue discussion on this
list - there is not much traffic on this list.

Kind regards, Jochen
