RVZSharp 1.1.1 Release Notes

RVZSharp 1.1.1 is a correctness and packaging patch. The public API stays compatible with 1.0.0 (validated at pack time against the published package via PackageValidationBaselineVersion), so upgrading is a drop-in.

dotnet add package RVZSharp

What's new

Zstandard encoder memory (max level)

• One-shot compression — ZstdEncoder now compresses each chunk with a single ZSTD_compress2 call (like Dolphin's ZstdCompressor) instead of a streaming session. A streaming session without a pledged source size reserves the level's full window before seeing any input (~128 MiB per worker at level 22), which exhausted memory when groups were compressed in parallel on modest machines; one-shot sizing caps the window at the chunk size. The output is unchanged standard Zstandard: a level-22 file decodes byte-identically in Dolphin's dolphin-tool.
• Pinned by Zstd_MaxLevel_ParallelRoundTrip plus a bidirectional dolphin-tool interop matrix (zstd, lzma, lzma2, bzip2, none at 2 MiB and 128 KiB blocks, both directions, SHA-1-compared against real game images).

Packaging

• No more empty symbols package — the assemblies carry embedded portable PDBs, so the .snupkg build carried no symbol files and nuget.org rejected it; only the .nupkg ships now. Debuggers read the embedded PDBs directly.

CLI downloads (1.1.1 bundles)

The 1.1.1 bundles are framework-dependent single-file executables: install the .NET 10 Runtime once, then unzip and run:

File	Platform
rvzsharp_v1.1.1_win-x64.zip	Windows 10/11, x64
rvzsharp_v1.1.1_win-arm64.zip	Windows 11, arm64
rvzsharp_v1.1.1_linux-x64.zip	Linux, x64
rvzsharp_v1.1.1_linux-arm64.zip	Linux, arm64
rvzsharp_v1.1.1_osx-x64.zip	macOS, Intel
rvzsharp_v1.1.1_osx-arm64.zip	macOS, Apple Silicon

Each zip holds the RVZSharp executable (RVZSharp.exe on Windows) plus LICENSE, README.md, WhatsNew.md and THIRD-PARTY-NOTICES.md. Verify downloads against SHA256SUMS.txt.

Trust, verified

• 610 library tests on each of net8.0/net9.0/net10.0 plus 57 CLI tests and a 276-test real-file suite (90 GameCube/Wii RVZ games decoded against their official No-Intro SHA-1s and re-encoded back to the same hash), plus a full dolphin-tool codec interop matrix in both directions.
• Audited against Dolphin's implementation and the rvz-1.0.3 Go reference; every divergence pinned by a regression test.
