The Lost Treasures of Infocom II CD (Activision, 1992)

Disc-specific material for archiving the Lost Treasures volume 2 CD-ROM. No disc content lives in this folder - only identification records, listings, notes.

A single 12.4 MB ISO 9660 data track, volume LOST TREASURES II, with Apple ISO extensions carrying both the MAC and DOS trees on one filesystem - the same shape as volume 1. Unlike volume 1, Redump has an entry for this disc (105382), and this dump verifies against it.

Contents

File What it is
disc-info.txt Captured drutil and diskutil output
lost-treasures-2-1992.ls.txt Recursive listing of the ISO volume
notes.md Per-disc findings
versions.md Release/serial table for every title, both platforms
checksums.txt Reference hashes for a full dump, Redump-verified

Archiving your own copy

  1. Insert the disc; confirm one session, one Mode 1 data track, 6075 blocks.

  2. Unmount and dump (seconds, at this size):

    diskutil unmountDisk /dev/diskN
dd if=/dev/rdiskN of="$HOME/Desktop/ltoi2-full-2352.bin" bs=2352 count=6075 status=progress
python3 ../../scripts/raw2user.py "$HOME/Desktop/ltoi2-full-2352.bin" "$HOME/Desktop/ltoi2-data.iso"
  3. Compare the printed hashes against checksums.txt; a match is a Redump-verified copy.

  4. Do not copy the Mac files from the mounted volume - macOS’s cd9660 driver cannot open the fork-bearing files (see volume 1’s notes). Extract from the image instead:

    python3 ../../scripts/appleiso.py "$HOME/Desktop/ltoi2-data.iso" "$HOME/Desktop/ltoi2-extracted"

Keep the raw .bin as the archival artifact and never modify it.
