I have the demos for th07-th013 on my Windows 8.1 computer, and I have patched them all using thcrap. However, none of the translations come up in the patched game. Is this normal?
Yes - as this issues implies, thcrap covers none of the demo versions before th14 yet. I will be adding support for them in the future. It might take a long time though, as this really is one of my lowest priorities at this point.
