The Elder Scrolls II: Daggerfall: 4 Open Source Clones Compared
Daggerfall Unity is the only actively maintained, fully playable option here, with cross-platform support (Windows/Linux/macOS) without emulation, high-resolution and widescreen rendering alongside optional retro display modes, and an active mod-creator community; it requires a free copy of DOS Daggerfall via Steam to supply its original assets. Daggerfall.NET and opendf are both listed as unplayable — the former's development has halted, and the latter, while still active, provides no further detail beyond needing the original Daggerfall data files. XL Engine is a multi-game engine — its config note lists Dagger, Dark, Blood, and Outlaws as supported games, not just Daggerfall — that's only semi-playable and whose own development has halted.
