<\/a>\n
\nLes changements:
\n
\nNew binaries<\/strong>
\n– Added D&D GUI App for Mac, Linux, Windows
\n– chdcomp binary with automatic –best compression (CD: cdzs,cdlz,cdzl,cdfl \/ DVD: zstd,lzma,zlib) now compresses to chdman default + zstd to get best compression
\n– benchmark binary for benchmarking chdman and chdlite
\n
\nFeatures<\/strong>
\n– Added function to take dir for -o and create output files with same name as input file.
\n– Default auto codec selection (smart default) now displays media type, platform and chosen codec. on compression.
\n
\nBug Fixes<\/strong>
\n– Restructured Toplevel chdlite command to api for gui\/cli compatibility.
\n– Added –version args.
\n– Fixed version display to 0.2.1 (Was 0.1.0 in 0.2.0)
\n– Fixed read not reading platform for ps1,ps2,pce chd.
\n– Fixed read not checking magic sector for pce even on cue read.
\n– Fixed -c chdman not passing codecs.
\n– delete chdman from -c –compression options, and only take actual codecs.
\n– Add -chdman, –chdman option for original codec compression.
\n– Add -best in addition to –best.
\n
\nSpeed Optimization<\/strong>
\n– zlib-ng integration
\n– xxHash AVX2 auto-dispatch
\n– LZMA encoder persistent instance
\n– FLAC 3\u21922 encode elimination
\n– CRC16 slice-by-16
\n– Sequential read hints (cross-platform)
\n– SHA1 SIMD dispatch
\n– CMakeLists.txt SIMD compile flags (-mavx2 -msse4.2 -mssse3)
\n– Per-file pipeline deferred hash computation
\n– N_SLOTS=3 triple-buffer pipeline
\n– Audio byte-swap auto-vectorization
\n– Remove 4-core cap on thread pool
\n– Multi-file batch thread budget
\n– Proper CUE sheet parsing for all disc formats
\n– Tests: 106 PASS \/ 1 FAIL
\n– Thread Distribution Optimized on multicodec trys. (Fixed issue where multicodec was slower than chdman. One codec per thread, distribution by codec complexity)
\n
\nLogging and Error Handling<\/strong>
\n– Dual-log system: Structured error.log (pipe-delimited) + command-specific pretty logs (chdread.log, chdhash.log, etc.)
\n–result flag: Pretty log on\/off control
\n-log
\n– N\/A logging for empty metadata fields
\n
\nOthers<\/strong>
\n– Extend read to support non-CHD files (ISO images, CD images, etc.)
\n– Terminology change: \u00ab\u00a0system\u00a0\u00bb \u2192 \u00ab\u00a0platform\u00a0\u00bb (detect_system \u2192 detect_game_platform)
\n–best compression preset for create command
\n-c chdman compression preset for create command
\n– Default -o flags for auto-generated output paths
\n– verify, copy, dumpmeta commands with full option support<\/em><\/p>\n
