Dune II (OpenDUNE)

Game: Dune II: The Building of a Dynasty → (DOS, 1992)

OpenDUNE: an open-source re-creation of Dune II, Westwood Studios’ real-time strategy game, so it runs natively on modern systems. It started in 2009 as a decompilation of the original executable, which at first ran on an x86 emulator (libemu) and which the team kept rewriting in C until version 0.6 (2011) converted the whole game and dropped the emulator. In its enhanced mode, the default, it fixes dozens of bugs in the original, such as reinforcements that only arrived once, buildings that degraded even on concrete slabs, or an AI that barely responded when you attacked its buildings, and a setting lets you play it exactly like the original, bugs included. It scales the image up to 4x with Scale2x or hqx filters, caps the frame rate at 60 fps by default, has fullscreen, and plays music over MIDI, including on an emulated Roland MT-32 (Munt) or with FluidSynth. It’s in English, French, and German. It runs on Windows, Linux, FreeBSD, and macOS, as well as Atari ST, STE, TT, and Falcon, OS/2, and Haiku. The latest release is 0.9 (May 25, 2018), and the project still gets changes: in 2026 it added support for stock Atari ST and STE machines.

You needThe version 1.07 data files from your own copy of Dune II for MS-DOS, DUNE2.EXE included; all three variants (eu, hs, and us) work, but French only works with eu and hs, and German only with eu. For MT-32 music through Munt, the CM-32L ROMs too. Plus Windows (32- or 64-bit), Linux or FreeBSD with SDL, or macOS.
