Hello Stephen,
Thanks for your reply, I have updated the copyright years and uploaded the package to mentors.d.n again.
I have also found and fixed another issue during the build: whenever libpython3-dev and cmake >= 3.0 are installed, python3 libraries were selected instead of python2.
Regarding the lowercase file issue, I haven't found any problem on my side. I was able to load and play Planescape: Torment and other games without modifying the filename case. Could you please give me more detail about the segfault (attach gemrb log, gdb backtrace, and / or open an dedicated bug)?
I haven't considered implementing support in game-data-packager as I didn't know it existed. I will have a look to see how this could be done.
