Decompressing Amiga archives: Ancient Format Decompressor
The "Ancient Format Decompressor" can decompress Amiga archives which were compressed on 16-Bit home computers using common compression programs. The source code can be compiled on every modern system. The following formats are currently supported:
  • CrunchMania by Thomas Schwarz: supports both new (version 2) and old stream formats:
    • CrM!: Crunch-Mania standard-mode
    • Crm!: Crunch-Mania standard-mode, sampled
    • CrM2: Crunch-Mania LZH-mode
    • Crm2: Crunch-Mania LZH-mode, sampled
  • Disk Masher System a.k.a. DMS
    • Supports all different compression methods (NONE,SIMPLE,QUICK,MEDIUM,DEEP,HEAVY1,HEAVY2)
    • Supports password bypassing
  • File Imploder (and most of its clones), specifically with following headers:
    • ATN!
    • BDPI
    • CHFI
    • EDAM
    • IMP!
    • M.H.
    • RDC9
    • FLT! (verification missing)
    • Dupa (verification missing)
    • PARA (verification missing)
  • PowerPacker
    • PP 1.1 (verification missing)
    • PP 2.0
  • Rob Northen compressors. supports all 3 known formats:
    • RNC1: Both old and formats utilizing the same header. heuristics for detecting the current one
    • RNC2: RNC version 2 stream
  • Turbo Packer by Wolfgang Mayerle.
  • Standard gzip
  • Standard bzip2, both normal and randomized
