What is the status of the data files license? I am unable to find this info anywhere. At this point we'd like to add the game to our official repository, but only software with clear license status can be hosted there.
Unfortunately the data is non-free; the original author only released the source as GPL, which means the data is "freeware". I've been trying to contact the author but I'm getting radio silence, I even found a linkedin profile which I'm almost certain is the same guy. I've also been slowly replacing the original data with free replacements
but it's going to take a long time. It's high on the list as it's also stopping the game from being included in other official repos, libregamewiki etc.
I'll let you know once it's done.
