Raw Normal View History

After extensive testing, the DarkPlaces and Quake 1.5 situation is in a slightly better shape. We have a more or less up to date engine, the mod comes with its own self-contained engine, and this has been tested on on amd64, arm64, ppc64 and x86 - and of those 4, only ppc64 had a showstopping issue - big endian support is broken in general in PNG loading facilities.
