Active Top 10 Native-Parity Work Items

Last reviewed: 2026-09-18

This is the current cross-game priority order. Each item is either actionable with the supplied original media or explicitly marked blocked by missing evidence. A fixture, a generated save, a guessed decoder, or an emulator runtime dependency is not an acceptable substitute. Firestaff must continue to read supplied game media in memory and run it natively.

Priority	Work item	Scope	Acceptance evidence	State
1	Complete the same-revision Nexus composed title/menu state	Nexus Saturn	A private same-session title capture now verifies Track 1 CD FIFO → Work RAM → instruction reads → VDP2 values, plus 162 contiguous VDP1/VDP2 hardware frames with nonzero VDP1 framebuffer/VRAM and VDP2 VRAM/CRAM/register domains. It still does not bind MAPD transformation to its display consumer and has no corresponding menu, HUD or dungeon capture.	Partly proven; consumer/menu/HUD/dungeon capture missing
2	Bind decoded Nexus PRS3 output to a real Saturn VDP1 consumer	Nexus Saturn	One original execution capture ties a hash-locked decoded `MENU.BPK` surface to its VDP1 destination, CLUT and command semantics. The Japanese retail Track 1 now proves all 162 PRS3 streams decode in RAM, with aggregate decoded-byte FNV-1a-64 `b60830cf2f601003`; this promotes the byte decoder only, never host rendering.	Blocked by missing capture
3	Capture Theron CD-to-RAM level-transition consumers	Theron JP and US	Authentic, revision-specific trace from Track 02 read through RAM consumer for at least one level transition per revision.	Blocked by missing trace
4	Obtain DM1 original runtime overlay pairs	DM1 PC 3.4	Hash-locked original and Firestaff captures for movement, HUD and viewport states; pixel/behaviour regression.	Blocked by missing captures
5	Bind CSB DSA-bearing original saves	CSB Atari, Amiga, FM Towns	Provenance/hash receipts plus native timer, transaction and DSA regressions per admitted edition.	Blocked by missing saves
6	Build CSB representative visual/audio comparisons	CSB Atari, Amiga, FM Towns	Original HUD, viewport, title, door and audio captures with native comparison gates. Native CLI and start-menu routes pass against supplied Atari STX, Amiga A31 and FM Towns retail archives; the FM Towns check also captures the real C28 + C002/C003 closed Entrance composition in Original, Modern and Custom and rejects the broad-red regression. Private, hash-bound emulator startup captures now exist for Atari ST (Hatari), Amiga (FS-UAE A1200/Kickstart 3.0; CPU-fault-free FTL title), and a first FM Towns CSB title frame (Tsugaru framebuffer, source archive/CUE/track/ROM hashes bound in its private receipt). The earlier A500 profile is explicitly rejected by the capture tool due to its emulated CPU exception. The Atari session also has a non-silent native WAV with no emulator audio warnings. No original HUD, viewport, door or same-state comparison capture is promoted.	Blocked by missing gameplay captures
7	Complete DM2 retail save ownership	DM2 DOS, Amiga, FM Towns, Mac	Authentic `SKSAVE`/record-pool/relocation corpus, fail-closed parser and save/resume regression for every admitted platform. The supplied DOS archive now binds all eight original SKSAVE primary/backup members to the native corpus regression; broader cross-platform save evidence remains incomplete.	Partly actionable; corpus limited
8	Extend DM2 retail gameplay receipts	DM2 DOS, Amiga, FM Towns, Mac	Real-media dialog/input ordering, AI/drop, audio and save/resume paths captured and natively regression-tested. CTest binds the supplied DOS, Amiga and Mac retail archives to native title, startup, New Game, Amiga LZX/resource, movie, audio and input receipts; the DOS `SONGLIST.DAT` table is read directly from its retail ZIP and the same original DOS dungeon now proves native pit, stair, door and active-creature runtime transitions in RAM. A private Tsugaru framebuffer receipt now binds the supplied FM Towns CD image, ROM set and an original title-sequence frame. Broader cross-platform gameplay remains open.	Partly actionable; corpus limited
9	Prove DM1 FM Towns audio and input	DM1 FM Towns	BIN/CUE in-memory track selection, CD-audio timing receipts and FM Towns-specific input-route tests. CTest derives actual CDDA ranges, TMenu poll/initialization/TBIOS entry bytes, RLE graphics-library corpus, and menu-font raster from ZIP→CUE→BIN→ISO9660 in RAM. It now also reaches `EDM.EXP` and verifies the complete public initial input matrix (forward, backward, both turns, both strafes, action) from separate real-disc sessions; low-level TownsOS event-queue capture remains open.	Partly actionable with supplied media
10	Prove DM1 Amiga planar presentation	DM1 Amiga	Original ADF-to-native planar image decode and representative pixel receipt; no PC-byte fallback. A real nested ADF record now decodes through the explicit big-endian Amiga IMG1 path into source palette indices; composed planar/palette presentation remains open.	Partly actionable with supplied media

Recently closed before this queue

The current queue starts after these verified fixes, so they must not be re-added as open work:

Nexus MENU.BPK PRS3 byte decoding is bounded and regression-locked directly from the supplied Japanese Track 1 in RAM. Its 162 real surfaces are deliberately held at the no-render boundary until Saturn presentation ownership is captured.
DM1 canonical and nested DOS ZIP startup routes are exercised through CLI, start menu and first movement.
Cracked-only DM1 Atari archive selection fails closed instead of selecting a nearby sibling.
CSB accepts supplied preservation ZIPs in memory; protected STX logical sector order is preserved even when payload offsets are skewed.
CSB’s supplied French preservation ZIP reaches title, runtime, first movement and start-menu launch through the native STX reader.
The supplied DM2 Macintosh First Chapter demo fails closed and cannot be mistaken for retail media.
Game-data archives are no longer materialized on disk by Firestaff.
Completion evidence records only the verified native-media scope above.

Selection rule for the next queue

When an item closes, replace it with the highest-impact item that has real media or capture evidence available. If the next item is evidence-blocked, keep that state visible rather than fabricating a substitute. Per-game detail and deferred data requests remain in TODO-dm1.md, TODO-csb.md, TODO-dm2.md, TODO-nexus.md, and TODO-theron.md.
