yuzu: bound the zip directory reads in the DLSS download

2026-11-03T18:06:59+00:00

The central-directory parser trusted each entry's name, extra and comment lengths and the Zip64 extra field's length, so a malformed directory could make it read past the downloaded buffer. The data comes from NVIDIA's GitHub release over TLS and the saved files are signature-checked, so the risk is low. Stop with an error when an entry runs past the directory, and read Zip64 fields only inside their record. Found by CodeRabbit review.

video_core, yuzu: write NVIDIA DLSS file paths to logs as UTF-8

2026-11-03T18:06:59+00:00

The Streamline start-up and DLSS download code formatted paths with std::filesystem::path::string(), which on MSVC converts to the active code page and throws when a character has no mapping there, for example a user name in another script under %APPDATA%. The start-up log runs inside the renderer's constructor, which only catches vk::Exception, so such a user would crash at game start with the setting on. Use Common::FS::PathToUTF8String for every path in these logs and messages. Found by CodeRabbit review.

yuzu: show NVIDIA's DLSS files in the Graphics tab and fetch them from NVIDIA

2026-11-03T17:33:16+00:00

Under the NVIDIA DLSS checkbox, a panel says whether the Streamline loader and DLSS were found and which versions, with "Open Folder" and a link to NVIDIA's Streamline releases. When files are missing, "Download from NVIDIA" takes only those files out of NVIDIA's Streamline 2.14.16 release zip on GitHub with HTTP range requests (about 1 MB for the loader, 32 MB with DLSS, of the 276 MB zip), after showing the Streamline and DLSS licence texts from the release for acceptance. Each file's CRC and signature are checked before it is saved to the user folder's "streamline" folder.

video_core: NVIDIA DLSS through NVIDIA Streamline in place of a game's DLSS

2026-11-03T17:33:16+00:00

Adds a Graphics setting, "Use NVIDIA DLSS in place of a game's DLSS" (nvidia_dlss, off by default). When it is on, in Windows builds configured with EGLANTINE_STREAMLINE_SDK, the evaluation Eglantine already replaces with FSR 3.1 goes to NVIDIA DLSS on GeForce RTX cards, with the same inputs (colour, depth, motion vectors, jitter). When DLSS can't run, FSR 3.1 runs as before. Only Streamline's MIT-licensed headers are compiled in; nothing of NVIDIA's is linked or shipped. At run time Eglantine looks for sl.interposer.dll in the user folder's "streamline" folder (or EDEN_STREAMLINE_DIR, or "streamline" next to the executable), checks its Streamline signature and starts Streamline with manual hooking. Streamline's plugins come from that folder or the NVIDIA app's downloads. DLSS itself is nvngx_dlss.dll in the same folder, else the newest DLSS 310 or later that the NVIDIA app has downloaded, checked for NVIDIA's Authenticode signature and copied as streamline/nvidia-app/nvngx_dlss.dll. Like other tools that call DLSS outside a game, it uses its own fixed project id with the custom engine type. - Preset K for all modes (EDEN_NX2_DLSS_PRESET overrides it): the default Performance model (M) and L draw thin dark horizontal lines in some frames at 2x resolution scale; K doesn't. - HDR input with auto exposure; the mode follows the render/output ratio. - Buffer device address stays enabled when DLSS needs it, for DLSS only. - The upscaler waits for the device instead of submitting when it is destroyed: by then the game's channels are released, and a submit read the state tracker's stale flags (a crash when stopping a game). With the setting off, or in builds without the SDK path (the setting is hidden there), nothing changes. Testing: Windows 11, RTX 5080, Fire Emblem: Fortune's Weave docked at 1x (720p -> 1440p) and 2x (1440p -> 2880p), CLI runs and GUI play, stopping and restarting games with DLSS on. Not tested on other GPUs or games. Assisted-by: Claude Opus 5.5 (implementation, debugging) Signed-off-by: Duck912 <350528965+Duck912@users.noreply.github.com>

qt: save frame generation settings (#283)

2026-11-02T07:35:22+00:00

Six frame generation settings are paired with frame_gen, so each widget made its own checkbox and saved it to frame_gen on apply. The last one won, so ticking only the first box left frame generation off. Don't make a checkbox for a paired setting without the Paired specialization. frame_gen is the only such setting, and it gets its own widget again. Keep the pairing itself, Android uses it to hide the options. On Qt, hide them while frame generation is off.

[settings,qt] merge of "disable controller applet" toggle with "controller applet mode" picker (#4498)

2026-09-29T22:57:23+00:00

- [x] I have read and followed the [Contribution Guidelines](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/CONTRIBUTING.md#code-contributions). - [x] I have read and followed the [AI Policy](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/docs/policies/AI.md) - [x] I have read and followed the [Coding Guidelines](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/docs/policies/Coding.md) to the best of my ability. ------------------- Small good simplification to nuke a toggle which costed me almost an entire day of work when fixing controller applet issues: There were two settings related to Controller applet: -"disable controller applet", which is a boolean toggle; -"controller configuration" applet mode, which is a "Real"/"Custom" picker; All i did was to nuke the toggle and add a third option "Disabled" to the picker. Users which used the disable toggle will have to pick Disabled; Real/Custom settings wont be affected since their indexes remains. All options tested against diablo 3. All working as intended.
