EverQuest Legends on NixOS via Wine

EverQuest Legends is distributed as a standalone Daybreak/LaunchPad installer, not through Steam. The flake provides an eqlegends app that creates a mutable Wine prefix and installs the launcher from a pinned Daybreak installer URL.

The installer is a Nullsoft/NSIS installer containing LaunchPad.exe, CEF libraries, and LaunchPad.ini with appName=EverQuest Legends and id=eqns. The game data itself is expected to be downloaded later by LaunchPad.

Quick start

Run:

nix run .#eqlegends

The flake fetches the installer from:

https://launch.daybreakgames.com/installer/EQLegends_setup.exe

To test a different installer, point the wrapper at it explicitly:

EQL_INSTALLER=/path/to/EQLegends_setup.exe nix run .#eqlegends

The Wine prefix lives at:

~/.local/share/eqlegends/wine

The wrapper installs LaunchPad to:

C:\Games\EverQuestLegends

inside that Wine prefix.

Useful environment variables

Variable	Use
EQL_INSTALLER=/path/to/EQLegends_setup.exe	Use an installer outside the current working directory.
EQL_WINEPREFIX=/path/to/prefix	Override the default Wine prefix location.
EQL_RESET_PREFIX=1	Delete and recreate the prefix before launching.
EQL_DXVK=1	Install DXVK DLLs into the prefix before launching.
EQL_FILTER_EGL_WARNINGS=0	Show repeated CEF/SwiftShader EGL probe warnings. Defaults to filtered.
EQL_WINEDEBUG=+seh,+tid	Override Wine debug logging. Defaults to -all.

There is also a reset helper:

nix run .#eqlegends-reset-prefix

If the flake app is installed into a profile, the helper is available as:

eqlegends-reset-prefix

DXVK

The wrapper defaults to WineD3D. Run with DXVK only if the game client needs it or performs better with Vulkan translation:

EQL_DXVK=1 nix run .#eqlegends

DXVK is copied into the prefix, so switching back to WineD3D requires a prefix reset:

EQL_RESET_PREFIX=1 nix run .#eqlegends

Troubleshooting

If the pinned installer hash fails, Daybreak probably replaced the installer. Update the fetchurl hash in packages/eqlegends/package.nix, or temporarily set EQL_INSTALLER.

The launcher may emit repeated libEGL warning lines while CEF probes graphics paths under Wine. The wrapper filters those by default. To see the raw output:

EQL_FILTER_EGL_WARNINGS=0 nix run .#eqlegends

If LaunchPad installs somewhere unexpected, inspect:

find ~/.local/share/eqlegends/wine/drive_c -iname LaunchPad.exe

The wrapper records the executable it launches in:

~/.local/share/eqlegends/wine/.eqlegends-launcher-path

If the launcher opens but renders as a blank CEF window, try a clean prefix first, then try DXVK:

EQL_RESET_PREFIX=1 nix run .#eqlegends
EQL_DXVK=1 nix run .#eqlegends

For verbose Wine logs:

EQL_WINEDEBUG=+seh,+tid,+loaddll nix run .#eqlegends
