Rednukem is a modern PC source port of various Build games, including Duke Nukem 3D, Redneck Rampage, Redneck Rampage Rides Again, and Duke Nukem 64. The port was created by Alexey "Nuke.YKT" Khokholov as an open source project built on the source code from EDuke32.
Port of Duke Nukem 64
A port of Duke Nukem 64 was added July 5, 2020. To play Duke Nukem 64 in Rednukem, simply place the Duke Nukem 64 ROM file (US or EU versions) into the Rednukem folder. When the Rednukem launcher opens, select Duke Nukem 64 under the list of games and leave the "Custom game content directory" as "None." The ROM file is not included with Rednukem and must be obtained separately.
