CydandClaude Fable 5 2ce3528f1c BT410 5.3.73: the bad pointer is the emulator's default-handler stub
The IVT scan on the second probe catch settles EBX: F000:CA60 is the
emulator's default unhandled-interrupt callback -- the value filling every
vector nobody hooked (it matched ~56 of them), while the hardware-IRQ block
IVT[08-0F] holds the DPMI host's own 0D1F reflector stubs.  The serial IRQs
are properly hooked; the host read one of the UNHOOKED vectors' default value
and probed [value + 0x3004] as a flat pointer, wrapping to the famous cr2.

Also corrected: the first dump read ESP/EIP as bare linear addresses -- the
'stack' bytes were DOS conventional memory (they decode as 16-bit real-mode
code), since SS=0107 has a nonzero base.  SegPhys-corrected dumps are built
and armed for the next catch.  The zeros at the faulting EIP are consistent
with DPMI32VM being a virtual-memory host that pages its own regions --
'Reference to a page you don't own' is its pager's abort message for an
address outside every region it owns.

Nailed: deterministic host-side path; the serial stream correlates as
exposure, not as trigger bytes; the bad read is [unhooked-vector-default +
0x3004].  Open: which vector, which host routine -- the corrected dumps
should name the return chain on the next catch.

Scene Restorations

Modern re-renderings of the Division dVS scenes recovered from the Glaze developer drive (see HISTORY.md) and this repo's CONTENT tree. The originals ran on Division Ltd.'s pixel-pipeline hardware in 19941997; these tools parse the original data files and re-render them in WebGL, in the browser.

Viewers (open in any browser, fully self-contained)

  • vwe-archive.html — the Scene Archive: 26 curated scenes across all projects — Star Trek (Enterprise-D, Klingon flyby), Hull Pressure (sea demos, fish schools, sunken temple), BattleTech (polar map with mech lineup, Ravine and desert maps, stadium), Red Planet (Blade arena, the Mars canal milestone demo), and the Canyon/Maya-temple Division demos. Fly camera: drag to look, WASD to fly, R resets.
  • trek-scn.html — the original standalone Star Trek restoration (TREK.SCN and KLNGVID.SCN).

Toolkit

  • divformats.py — parsers for every Division format found on the drive: text VGF/VMF (DIV-VIZ2 geometry/materials, both the 1995 VERSION 2:07 and 1996 02:05 dialects, with header SCALE support), binary BGF/BMF (DIV-BIZ2) — the binary block-stream layout was recovered from Division's own reader source (DPL3/BIZREAD.C, 1994), including all 14 vertex layouts, pmesh/tristrip/polygon connectivity, LOD blocks (newer writers nest patches inside LODs; the largest LOD is taken), and embedded materials/textures/ramps — plus TGA and raw SVT textures, SPL splines, and SCN scene scripts.
  • audit.py — scans every .SCN on the drive and reports what fraction of its geometry survives, and in which format.
  • extract_all.py — extracts every scene with ≥60 % of its geometry recoverable (108 of 241 on the drive; the rest reference lost models) into allscenes.json, resolving models/materials/textures across the drive and this repo's CONTENT dirs.
  • gallery_build.py — curates scenes from allscenes.json into the self-contained vwe-archive.html (via gallery_template.html).
  • convert.py / viewer_template.html — the original single-scene Star Trek pipeline.

Fidelity notes

Faithful: vertices, triangles, material colors and shading ramps, textures, fog and light parameters, spline motion, camera start positions. Approximated: Division's rasterizer behavior, point sizes, timing (originals ran at 30 Hz). Not simulated: event-driven SPECIALFX particles. A few dev scenes had camera start positions inside geometry; those get overridden or auto-framed cameras (see START_OVERRIDE in gallery_build.py). Scenes missing one or more models from the drive say so in their header.
