What's new since build 65

Game fixes

• Star Fox: it now renders instead of showing a black screen. Its DLSS network goes through Lichii's de-jitter stand-in, which stops the heavy smearing and stretched geometry (#45, #46). The ULDC.U16 shader lowering is in (#45). Controller input works through HID command 300 (#64). The MSVC build of its colour match is fixed (#76).
• Donkey Kong Bananza: fixes the crash after cutscenes and cuts the stutter from command-page draining on the split GPU thread (#70). Atomic compute shaders, pacing and descriptor fixes are in (#45). It runs well, though not at a locked 60 fps yet.
• Kirby Air Riders: fixes the white world (#56). Texture arrays with separate samplers no longer break, and the pipeline cache is now v50, so shaders rebuild once (#65). Shader translation is faster, and pipelines the game is waiting on now build immediately instead of queueing, so race stalls are shorter (#71).
• Mario Tennis Fever: fixes the device loss when the first court loads (#38).
• Nintendo Switch Sports Resort: system mixer audio in S16 format now plays (#75), with upstream's #472 fixes ported (#62).
• Yoshi and the Mysterious Book (demo): lowers the full-width IMNMX and buffer-reduction shaders (#66), and ports upstream's #123 shader subset and #502 video fixes (#62).
• Mario Kart World: the 30 fps mode and dynamic fps options from upstream #403 are under Graphics → Advanced (#45).

Video playback

• Ports upstream's H.264 framing, GPU-mapped presentation, end-of-stream readiness and bounded queue (#41 via #45).
• Compressed video inputs are kept beyond the readiness watermark (#49), and readiness notifications stop during teardown (#48).

Emulation and GPU

• Merges upstream Eglantine three times (#37, #42, #50). This brings in upstream's video decode fixes, per-draw GPU back-thread trims, DLSS through Streamline, the controller font fix and a tessellation guard (#426).
• Shader lowering adds native BRA.U (#55), Ampere register-handle image loads and stores (#57), uniform shifts with an immediate high word (#58), geometry and FMUL fixes (#56), signed relocation compares (#74), and atomics behind unmapped native pointers (#47).
• Split GPU thread: the thread is no longer drained before every pushbuffer entry (#54), and front-side buffer flushes run on the back thread (#59).
• Upstream safety ports from #329, #475 and #505, including range and syncpoint guards, swapchain recovery, the compute subgroup size check and the Polish language code (#62).

macOS

• Apple silicon: fastmem on 16 KiB pages, MoltenVK submission and render-pass work, and video session fixes. Measured in Mario Kart World on an M4 Pro, races went from about 9.5 fps to 30–38 fps (#22).
• Fixes the macOS build that failed in the window trace (#77).

Diagnostics (all off by default)

• NVIDIA Aftermath crash dumps are kept across launches (#67).
• Frame dumps, render, video and IPC tracing, the shader sweep and static shader extraction tools (#44, #60, #69, #71).

Known issues

• Star Fox gameplay is capped at about 30 fps, even though the game asks for 60. We're tracing the cause.
• Star Fox on RTX 50-series GPUs (5070 Ti, 5090) can lose the GPU device shortly after a scene change. If this happens to you, try NVIDIA driver 610.88.
• "Failed to allocate 14336 MiB of backing memory" means Windows ran out of RAM plus page file. Set the page file to system-managed and close memory-heavy apps.
• Yoshi demo: some textures are still black, and it can crash later in play.
• Kirby Air Riders: some races still stall while shaders build.

Automatic build of nx2 at 286117c.

Linux

Linux packages come as an AppImage (self-contained, needs glibc 2.39 or newer: Ubuntu 24.04, Fedora 40, Debian 13, Arch) and a tar.gz (uses your system libraries, so Qt 6 and the usual libraries must be installed).

Windows

Windows packages are in-place zip files: extract and run lichii.exe, or eden-cli.exe from a terminal.

macOS

The PGO builds are the same programs compiled with profile-guided optimization (clang plus Eglantine's profile); prefer them when your CPU supports it.
