Missing Functions and Verification by Game

Status: 2026-08-27. This is a summary of Firestaff’s remaining gaps, not a list of every historical TODO or symbol name.

Each item is classified as follows:

Missing code – the function or its production route is not implemented.
Missing original data – the source format or a sufficient corpus is unavailable.
Missing verification – the route exists, but needs authentic runtime, pixel, or capture evidence before it can be considered complete.
Intentionally closed – a synthetic or uncertain route must not be reopened.

The respective game TODO is the source for detail: DM1, DM2, CSB, Nexus, and Theron.

DM1

Missing Original Data or Evidence

Authentic C13 save: no local PC34 save is verified to contain the requested C13 event. Existing saves provide C03/C04 data, but do not replace a C13 corpus.
Original-versus-Firestaff pixel pairs: broader pairs are missing for the viewport, creature chain, champion HUD, panels, launcher, effects, and macOS/app runs.
Original capture of C13/HoC/top-row/action routes: capture scripts and source gates exist, but coverage is incomplete.
FM Towns: some TownsOS EGB pixel semantics and mouse/input routing still depend on capture/BIOS evidence. This concerns original parity, not Firestaff’s native launch route: the authentic FM Towns ZIP starts without a BIOS.

Missing or Incomplete Functionality

Broader sensor, removal, and DSA interactions still need source-owned original-save/runtime evidence.
The creature and combat chain has verified parts, but broader group layout, creature combat, and additional timeline cases are not fully proven.
DM1 V2.2 lacks a reviewed, authentic material package and complete source-owned modern presentation. Placeholder/procedural art must not be activated as a replacement.

Not a Remaining Production Gap

DM1 V1’s normal PC34 viewport, HUD, inventory, and action routes have source gates and fail-closed behaviour. The word “synthetic” in receipts, negative probes, or ReDMCSB’s own synthetic wall terminology does not by itself mean that production code draws synthetic DM1 pixels.

Native startup matrix (verified 2026-08-29): Firestaff reads the real media directly in memory and reaches dm1-runtime with levelLoaded=1 from both the CLI and start menu for ten supplied release routes: English DOS 3.4 ZIP, French DOS after manual RAR2 extraction, Atari ST English outer/nested ZIP, Atari ST German and French preservation ZIPs, Amiga HD and 2.0 ZIP → ADF, and FM Towns JA/EN ZIP. The focused dm1_v1_*_cli_boot CTests check the canonical asset MD5 and never use an emulator or BIOS at runtime. The authentic French DMSAVE.DAT/.BAK pair additionally passes a source-backed F0435 → F0433 → F0435 round trip against its original DUNGEON.DAT; party, C03/C04 timeline and active groups remain intact. This is startup/save evidence, not a claim of complete original pixel or game-system parity.

DM2

Missing Code or an Incomplete Production Route

Database ownership: Firestaff’s DM2 model still needs fully validated original record pools, links, maps, and relocation semantics instead of the reduced save-state layout.
Input and dialog: the original resume selector, keyboard/mouse ordering, held-button semantics, modal dialog, text, cancel, and event-queue behaviour are incomplete.
Creature drop/AI: AI tables and parts of the drop route exist, but source-owned CREATURE_AI records must be bound to graphics, possession, death, and cooldown before the route can be considered complete.
Save/load and GAME_LOAD: the SKSAVE format and remaining runtime-state ownership need a broader original corpus and packaged-app verification.
CCM and cell effects: advanced DM2_PROCEED_CCM, complete cell-content digest/map changes, and teleporter effects are not fully implemented.
V2.2 rendering: real material/pixel consumption, clipping, additional depth/outdoor routes, and runtime wiring are missing.
V2 HUD: authentic text/bitmap assets and more widgets, including inventory quick-view and action prompts, are missing.

Missing Original Data or Verification

Weather needs original save/memory snapshots that bind the timer record to its correct owner and change.
A complete DOS framebuffer/blitter capture is needed for palette/clipping parity.
MIDI and some runtime sound owners lack instruction-level traces and source-bound save/runtime evidence.
Demo and non-PC extracts need separate version/container classification.

Intentionally Closed

examples/dm2_hud_widget_synthetic/ and procedural V2.2 art are gate fixtures only. They must not replace the real DM2 GDAT source or be presented as completed Skullkeep graphics.

Native startup matrix (verified 2026-08-29): authentic DOS English and French, Amiga, FM Towns, and Macintosh ZIPs are read in memory. Both DOS editions retain their own authenticated GDAT/GAME_LOAD startup owner through SKULL and New Game; Amiga follows its TITLE stream to runtime; FM Towns follows AUTOEXEC/TWANIM to GDAT’s New Game rectangle and the source-owned champion selection click; Mac starts the verified retail profile. DM2 DOS MVE can also be verified headlessly with source-ordered presentation frames in dm2_v1_dos_native_cli_boot. This is startup/runtime evidence, not complete parity for saves, rendering, AI, or audio.

CSB

Missing Original Data or Evidence

CSBWin DSA corpus: a checksum-validated DSA-bearing CSBWin save with index/action records is needed for positive breadth.
Save corpus per media/version: a verified original save and round-trip proof are needed for every claimed media/version branch.
Real capture: broader original capture of the HUD, viewport, title, doors, and macOS/app/other media branches is missing.
Audio: complete audio/runtime parity with source-owned dispatch is not complete.

Missing or Incomplete Functionality

Deeper end-to-end gameplay parity and playability without DM1 assumptions.
More DSA timer, generator, teleporter, and sensor transactions with authentic save/dungeon pairs.
Broader source-locked viewport placements, masks, material bindings, and draw order for CSB-specific D2/D3 routes.
V2.2 needs a real PC34 GRAPHICS.DAT-based material/pixel binding before modern art can be re-enabled.

Intentionally Closed

The synthetic dungeon-loader/world fixture and experimental launch fixtures may continue to test lifecycle and negative branches. They are not substitutes for CSB’s real dungeon, save, or viewport data.

Native startup matrix (verified 2026-08-27): Firestaff reads real CSB media in memory and performs the original title → runtime → first movement sequence, as well as the start-menu launch handoff, for Atari ST (raw STX and nested ZIP), Amiga ADF archives, and FM Towns CD archives (English and Japanese program chains). csb_v1_{atari_stx,atari_nested_zip,amiga,fmtowns_{en,ja}}_native_cli_* proves these routes. Startup evidence does not replace the open original-capture and DSA/save-parity requirements above.

Nexus

Missing Code or an Incomplete Production Route

Structure2 material: complete descriptor, UV, texture, and palette semantics are missing for binding raw descriptors to renderable material.
Animated material: payload grammar, sequence semantics, flags, and timing are incomplete.
Saturn runtime/capture: a real executable/emulator trace and frame capture are required for pixel position, mode, palette, and timing. Static ISO inspection is insufficient.
Audio: CUE-declared retail BIN tracks are now source-bound; Saturn’s dispatcher, native decoder, literal sample/trigger evidence, and playback are still missing.
Structure1F/VDP1: several material, texture/palette, and replay gates remain capture- or host-route-dependent.
VDP2 NBG1 tilemap: corrected Saturn word/byte address and character-stride math was merged in PR #19; the capture-only test does not provide a retail asset owner, text/page mapping, placement or production rendering.

Missing Original Data or Verification

A complete Saturn run, including the BIOS/emulator/capture chain, is the primary external gap.
Original LEV*.DGN, SLEV*.BIN, SNDLEV*.SAL, and *.MNS files are available locally, but raw bytes are insufficient evidence for semantic material, gameplay, or animation interpretation.

Intentionally Closed

Generated DGN/DMDF/save fixtures may be used for parser and round-trip tests. They must not be promoted to a playable Nexus world or used as Saturn pixel evidence.

Theron

Missing Original Data or Verification

Save body layout: SRM/save correlation and the complete body layout are not sufficiently source-locked.
Original/Firestaff paired capture: the shared v2 comparator now requires hash-bound authentic-media and --debug build receipts per checkpoint, but a same-state original-versus-Firestaff image pair and reviewed receipt producers are still missing.
Startup media: authentic decoding and pixel evidence for Track 02 startup art, text, and audio are missing.
Post-$3800 chain: the continuation consumer after the authenticated $3800 boundary needs further live capture.
JP runtime: Japanese-specific media/capture verification and some offset questions remain; they must not be derived from US data.
Broader original corpus: more authentic CUE/BIN/ISO combinations are needed for version and media breadth.

Missing or Incomplete Functionality

JP runtime is limited: the authentic JP Rev 1 CUE reaches native title → stage → Soul Room → Akutuba and can source-bind Drator, but this is not broad gameplay or transition parity.
Complete source-owned semantics for later levels, objects, champion data, and save/load are incomplete.
Authentic runtime traces are needed for doors, pits, teleporters, altars, combat, drops, and sounds outside the already verified level-0/table slices.
A complete Track 02 bitmap/material decoder and production-bound viewport/UI presentation are missing.
V2.2 lacks an authenticated Track 02 material package; procedural/AI art must remain fixture-only.

Intentionally Closed

No-op, fixture-start, and synthetic parser routes must not create a replacement level when authentic Track 02 records are unavailable. Production remains capture-gated.

Shared Priority Order

Obtain or verify the missing authentic save, media, or capture source.
Bind bytes to the correct original function, record owner, and runtime route.
Add a source lock and real-data regression.
Add original-versus-Firestaff pixel or timing pairs where the function is visual.
Keep uncertain or missing data fail-closed; do not create synthetic saves, frames, roster data, or material to fill a gap.
