This page presents NetHack brass as a patch against vanilla NetHack 3.4.3. Kernigh used the diff program to generate this "unified diff" between NetHack 3.4.3 and NetHack brass 040923 after pruning some files from the 040923. In particular, Youkan's zip of the 040923 source code was not clean of generated files created during the build process on Microsoft Windows, including some Windows executables. Youkan's zip also contains old versions of some of the dungeon files, with DOS batch (*.bat) scripts to enable them. Download the patch from:
