About:
Lhasa is a free, open-source implementation of the LHA (LHarc) data compression algorithm. It provides robust tools for decompressing and extracting files from .lzh and .lzs archives, which are commonly used with older software and games. This utility is essential for accessing legacy archives on modern systems without proprietary software.
Key Features:
  • Command-line utility for decompressing LHA archives
  • Supports both .lzh and .lzs file formats
  • Portable and lightweight C library implementation
  • Robust error handling and archive validation
Use Cases:
  • Extracting legacy software or game archives from the 80s and 90s
  • Automating the decompression of LHA files in build scripts or CI/CD pipelines
  • Developing custom applications that need to read LHA-compressed data
Alternatives:
  • unar – unar is a more universal tool that supports many formats including LHA, but Lhasa is a focused, lightweight solution specifically for LHA.
