externals: add the FSR 3.1 upscaler shaders from AMD's FidelityFX SDK

2026-11-02T21:28:01+00:00

The GPU half of AMD FidelityFX Super Resolution 3.1.4, unmodified, from FidelityFX SDK v1.1.4 (commit c6efa6bf7f20, MIT): the GLSL headers (core, fsr3upscaler, spd, fsr1) and the eight Vulkan upscaling pass files. The next commit compiles them with glslangValidator in host_shaders like the other shaders. No prebuilt binary, DLL or AMD tool from the SDK is used, and the HLSL callbacks, the autogen-reactive pass and the debug view are left out. REUSE entry added for the directory.

nx2: play AV1 movies (FFmpeg with dav1d on Windows and Linux x86_64)

externals: FFmpeg with AV1 on Windows and Linux x86_64

2026-11-01T15:29:07+00:00

crueter-ci's FFmpeg packages have no AV1 decoder, so the AV1 movies of Switch 2 titles (Fire Emblem: Fortune's Weave) could not play. Windows (MSVC) and Linux x86_64 builds now use Takoroka/ffmpeg-av1 9.0.2-av1-1: the same FFmpeg commit, patch and configure flags as crueter-ci's 9.0.2-1790726865-946fcce07b, plus libdav1d 1.5.4 merged into avcodec. Other platforms keep crueter-ci's packages.

[loader] add ZBIC (zstd variant) NSO decompression support for Switch 22.0+ (#4482)

This is a customized variant of zstd and is used when NSO flags have bit 7 set. Key characteristics: - ZSTD_MAGICNUMBER is set to 0x4349425A (b'ZBIC') instead of 0xFD2FB528 - ZSTD_LEGACY_SUPPORT is set to 0 - ZSTD_TRACE is set to 1, zstd version used is 1.5.7 (10507) - FSE_readNCount is replaced with a BIC (Binary Interpolative Coding) version which improves compression of entropy tables significantly Source: https://switchbrew.org/wiki/22.0.0 Implementation: - Detect ZBIC segments via NSO flag bit 7 (NsoFlags_UseZbicCompression) and/or ZBIC magic scan in nso.cpp - Fall back to LZ4 when ZBIC is not detected or returns unexpected size - Handle segment 0 alternate offset (0x100 vs 0x108) for both ZBIC and LZ4 References: - Atmosphère loader/strat zstd-zbic integration: https://github.com/Atmosphere-NX/Atmosphere/commit/082115187a0509cb6b8a757de639a4e4741b8712 - nxdumptool ZBIC segment compression support: https://github.com/DarkMatterCore/nxdumptool/commit/441e5c0904f29427987433be4eb057a2843d222a - STORM_SWITCH ZBIC implementation: https://github.com/ReiKatari/STORM_SWITCH/commit/1e09eb82b760aaf340b810031400991c0740c091 Tested with firmware 23.0.0 and ZBIC-compressed NSOs.

[vulkan, android] Add feature of post-processing shaders on Android (#4348)

2026-09-10T13:14:02+00:00

Very self-explanatory; implementation of the feature for post-processing shaders for Android (at least for now); will allow users to enhance the graphic quality of video games based on the use of multiple shaders adjustable, presets and more, inspired on the PPSSPP implementation, this feature adds 22 customizable shaders (1 pass) that lives on the overlay of the screen, which means that aside of the capability to chain multiple shaders on the screen, this doesn't have depths (pixel/ depth z-buffer) so it ensures the performance with it's use. Few shaders were a faithful port from PPSSPP with their respective attribution on the shader headers for their respective owners; and there are adaptations from public references/ cinematographic (Anime4K) and the rest are my own addition. _Special Credits:_ 1.- PPSSPP Team for their contribution on the public references for shaders: Henrik Rydgard, ShadX, SimoneT, KillaMaaki and guest(r). 2.- Niklas Haas. 3.- bloc97.

[android] Replace Oboe audio with SDL3 audio (#4338)

2026-09-01T22:29:58+00:00

Supersedes #4335. Replaces the Oboe audio backend with SDL3, since we already support it. A few caveats: - SDL defines a JVM OnLoad method already, so we have to instead hijack NativeLibrary for id_cache initialization - This also means some internal fields in Double/Integer/Boolean (namely `value`) can't be accessed, so I switched those to methods for now. - SDL Java sources are pulled in from the CI package. - Since we can't use SDLActivity, `SDL.setupJNI()` handles everything Signed-off-by: crueter - [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. ------------------- Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/4338 Reviewed-by: Lizzie and Samuel Reviewed-by: MaranBr

[common] Switch to boost::unordered_flat containers (#4326)

2026-08-31T00:58:09+00:00

Replaces all instances of ankerl's unordered map/set with boost's `unordered_flat_*` classes. This uses std::hash since boost::hash is actually a lot slower. Also adds an abstraction layer in `Common` so future changes are quicker and easier. Other implementation details: - ankerl provided hash specializations for tuple and pair, so those were ported here - std::erase_if doesn't work on boost, so just used the ADL'd erase_if This should be about equal or superior performance as unordered_dense for everything except iteration.
