v2.1.0

v2.1.0

New Texture Format Support

Based on work by @heisthecat31 (PR #5), cleaned up and tested:

• R8_UNORM — Grayscale textures
• R8G8B8A8 — Uncompressed RGBA (sRGB and linear)
• B8G8R8A8 — Uncompressed BGRA (sRGB and Typeless)
• R11G11B10_FLOAT — Packed HDR float format

Fixes

• RGB565 bit expansion — Fixed rounding errors in BC1/BC3 color decoding (bit-replication instead of lossy multiply-divide)
• sRGB interpolation — BC1/BC3 now interpolate in linear space for sRGB variants, producing correct colors
• NRGBA output — Decoded textures now use non-premultiplied alpha (image.NRGBA), which is correct for texture data

v2.0.0

Breaking Changes

• Extract output format changed: Extracted files now include format extensions (.dds, .ogg, .bin, etc.) based on magic-byte detection
• Sidecar extension changed: Sidecar metadata files now use .evrmeta instead of .meta to avoid collision with TextureMetadata assets
• Scanner parsing fixed: File/type symbols are now parsed as hexadecimal (was incorrectly base-10), which changes how the scanner interprets directory names

New Features

• Lossless codec pipeline: DDS headers are automatically added/stripped during extract/pack for seamless round-trips
• Patch mode (-mode patch): Replace individual files in EVR packages without full rebuild
• Search mode (-mode search): Find assets by symbol hash, type, or filename pattern
• Audio detection (pkg/audio): Format detection and metadata parsing for OGG, WAV, MP3, FLAC
• Sidecar metadata: .evrmeta JSON files preserve symbol IDs through friendly-named extraction for deterministic repackaging
• Named extraction: -wordlist flag maps hex symbols to human-readable filenames
• Batch extraction (batchextract): Parallel extraction of all packages with worker pool
• Wordlist builder (buildwordlist): Harvest 52K+ symbol names from evr-reconstruction data

Bug Fixes

• Fix scanner base-10 parsing of hex symbol filenames
• Fix scanner failing on filenames with extensions
• Fix .meta sidecar extension collision with TypeTextureMetadata
• Fix TypeName formatting negative int64 values with wrong hex output
• Fix PatchFile not shifting FrameIndex for other entries after frame insertion (data corruption)
• Fix duplicate WAV/RIFF magic signatures in analyze mode
• Remove dead test assertion in SNSMessageHash test
• Remove unused magicReadSize constant, bytesToFloat32 function, custom max helper
• Add missing error check for f.Seek in texconv DDS decode
• Validate -algo flag in symhash (was silently falling through on typos)
• Remove unused -filter flag from batchextract
• Validate -workers flag in batchextract
