A word of explanation: LTF Abandonware France is one of the affiliate partners of GOG.com. We have signed an agreement with the site's owners, thanks to which they present GOG.com as a place to legally get a copy of the old games and receive a percentage from the sales made via their link. That's why you can see direct links to the GOG.com game pages and a link to our main page in the "Official partners" section.
Hope this clears things out :)
