x86_64 or ARM64
Most Linux desktops, laptops, and Steam Deck devices should use the x86_64 AppImage. The ARM64 AppImage is only for compatible ARM Linux hardware.

Download the AppImage for your CPU, mark it executable, and start Dusklight from your file manager or terminal. Then choose Select Disc Image and pick your own supported GameCube dump. The Linux notes below cover Vulkan, FUSE, distro differences, GLIBC, and AppImage permissions.

The official v1.3.1 release publishes Dusklight-v1.3.1-linux-x86_64.AppImage for most Linux PCs and Steam Deck, plus Dusklight-v1.3.1-linux-arm64.AppImage for compatible ARM Linux devices. The README keeps the core setup short: download, launch, Select Disc Image, and Play. This Linux guide adds the details that affect real installs without inventing packaging promises: AppImage handling can differ by distribution, Vulkan driver maturity matters, and older issue reports show why checking terminal output is better than repeatedly redownloading the same file.

The official README lists D3D12, Vulkan, or Metal as the graphics backend baseline. On Linux, Vulkan driver support and Mesa or vendor driver quality usually determine whether launch succeeds.
Some distributions need AppImage or FUSE support installed before an AppImage opens normally. If double-clicking does nothing, terminal output is the fastest diagnostic path.
The supported game input remains your own dump of the GameCube USA or EUR release. Do not follow guides that direct Linux users toward ROM mirrors or unsupported Wii files.
Linux users have the best diagnostic tools if they keep the terminal path clean. These commands verify the file, set executable permission, and run the AppImage in a way that makes driver and library messages visible.
sha256sum ./Dusklight-v1.3.1-linux-x86_64.AppImageUse this after downloading from GitHub. GitHub release asset metadata includes a SHA-256 digest, so a careful user can compare the value before launching.
chmod +x ./Dusklight-v1.3.1-linux-x86_64.AppImageThis is the standard fix when a desktop environment treats the AppImage as a plain file. It does not install copyrighted game data or modify your dump.
./Dusklight-v1.3.1-linux-x86_64.AppImageIf the window does not appear, keep the terminal output. Messages about GLIBC_2.39, Vulkan, FUSE, or missing graphics support are much more actionable than saying the AppImage did nothing.
Stay in this language while comparing Dusk Light downloads, file sizes, update times, and platform notes.
The Linux page is based on v1.3.1, the latest GitHub release checked on June 16, 2026. The release lists the Linux x86_64 AppImage at 31.6 MB and the Linux ARM64 AppImage at 30.8 MB.
v1.3.1 includes configuration saving and loading fixes plus improved crash reporting in log files. That is especially useful on Linux because terminal logs and crash logs can reveal driver or runtime-library problems.
The same release notes mention missing chains in Arbiter's Grounds and Hyrule Castle. Linux visitors should update before troubleshooting a gameplay issue already addressed in the current build.
A Pop!_OS AppImage report showed terminal errors mentioning GLIBC_2.39 and related library versions. It is closed as not planned, but it is still useful evidence that older distributions can fail before the game window appears.
Open sourceA Linux feature request says the AppImage appeared to default to one GPU even when the user tried environment variables and vkconfig. Multi-GPU users should record GPU details when reporting launch or performance problems.
Open sourceA Linux request asked for raw AppImage assets to make AppImage managers easier to use. It is marked completed, which matches the current v1.3.1 release publishing AppImage files directly.
Open sourceA closed Linux report discussed AppImage portable mode behavior. It is useful context for users who expect .home or .config folders beside the AppImage to behave like every other AppImage.
