playable xiso

a playable xiso rebuilds the XDVDFS game filesystem into a smaller conventional layout for xemu. it does not retain the physical mastering layout.

full disc

a full-disc image retains the accessible physical address space. gdox stores hashes, a manifest, unreadable ranges, and available drive evidence beside it.

full length does not by itself make the image security-sector-complete or redump-complete. gdox records those claims separately.

verification

when verification is enabled, gdox hashes the output while writing, closes it, reads the completed file again, and requires both hash sets to match before publishing the final name.

the complete format and evidence boundaries are in PRESERVATION.md.
