free packages in nonfree repo

Hi list, today I realised that there are two sldmame frontends in the nonfree repo (qmc2 and gnome-video-arcade), which are perfectly free themselves as licensed under GPL. Since these pieces of software are pretty much useless without sdlmame, they were put into the nonfree repo, and have sdlmame present in their Requires. Do you think they should stay in nonfree, or rather be moved to free? And what with requires then? Regards, Julian
