Hi Franko
I am not 100% sure about this, but I think Amiga Forever now own rights to the Amiga Kickstart Roms, they were included on the purchased CD / DVD.
Some of the games are still copyright by there original owners eg.
Team 17, Psygnosis (Sony), Electronic Arts, Cinemaware
http://www.cinemaware.com/ .
Take a look at Back to the Roots website
http://www.back2roots.org/ they have a policy on the site if a game or image is copyright and it belongs to you, contact them and they will remove the file.
Might be an idea to speak to Lemon Amiga admins
http://www.lemonamiga.com/ admins as they have a ton of Electronic Arts games on thier site.
PS Commodore Scotland is a nice site well done mate.
