macOS: fix the build with AppleClang and use the Eglantine app icon

2026-10-31T22:16:44+00:00

The zbic_compression.cpp warning suppressions only matched the Clang and GNU compiler IDs, so AppleClang failed it with -Werror=unused-function. The bundle pointed at dist/eglantine.icns, which was never added after the rename (and the fallback to eden.icns shows Eden's logo); generate it from dist/Eglantine.png and use it.

video_core: less waiting on the GPU caches' locks

2026-10-29T05:51:42+00:00

- The texture and buffer caches' mutexes spin briefly before sleeping (Common::SpinRecursiveMutex): the GPU thread, the fencing thread and CPU write traps take them tens of thousands of times a second for microseconds, and a sleeping waiter's wake-up took longer than that. Title 1's GPU thread slept 7.7% of its time there, now 3.7%. - Fences commit and pop texture and buffer downloads separately, and only when there are any (one fence per compute dispatch in Switch 2 titles): the fencing thread no longer holds both caches while it copies buffer downloads. - Inline uploads and pre-draw invalidation take the caches one at a time again: holding one while std::lock waited for the other waited longer.

Fix build with MSVC 14.51 (VS 2026)

2026-10-27T15:46:04+00:00

- sparse_large_vector: ULONG_PTR -> u64 needs static_cast, not reinterpret_cast - zbic_compression: silence C4505/C5245 for the amalgamated zstd.c, which is compiled as project code and hits /we4505 - launch_params: explicit int -> bool (C4800 is an error here)

[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.

[common] Use `std::make_unique_for_overwrite` in ScratchBuffer, remove polyfill (#4432)

2026-09-25T05:54:49+00:00

Original `make_unique_for_overwrite.h` is well defined acc. to standard https://en.cppreference.com/cpp/memory/unique_ptr/make_unique, but by now most libc++ supports the function, so no need for polyfill. Test that this didn't break anything (for example, Megaman game that has video at the start), or anything using VIC/IPC.

[common] Replace `Common::SpinLock` with `std::mutex` (#4436)

[common/core/dynarmic] Optimize page table allocations (#4219)

2026-09-09T19:35:49+00:00

Reduces the page entries from 32 bytes to 8 and rewrites `VirtualBuffer` to be more efficient in memory usage and specifically for large zero regions. The page table will now only reserve 1GiB instead of 4GiB and of this memory it should only use at most ~8MiB. This PR has the side effect of using Eden on Windows on low memory systems much more plausible since it would previously require ~10GiB of committable memory at front (despite using ~5-6 at most, inadvertently stalling other processes) where as now it should only require around the amount that it'll actually use.

[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.
