seedds 3a993fa3fe Subsystem references and a symptom index: the failure catalogue of docs/agents/03-bringup.md and the per-title material of docs/agents/04-graphics.md (section 1's container list, section 6 and its "Seen in <game>" subsections) move into docs/reference/, one heading per mechanism: rewriter.md, memory.md, threads.md, services.md, movies.md, audio.md, frame-rate.md, nvn-objects.md, rendering.md (with the Vulkan and OpenGL layers), shaders.md and game-state.md, indexed by docs/reference/README.md. Each entry gives the symptom, the cause, the fix (file and function), the games it was found on (linked to their notes in dm/games/<id>/README.md) and any check, caveat or later change; one mechanism met on several games is one entry. docs/agents/symptoms.md lists every entry's symptom (an assertion, a [RED] line, an abort or crash site, a visible result) with a link to it, 350 lines, generated from the Symptom bullets. 03 keeps the loop and reading the log, and its Failure catalogue section now points to the references, the index and where a new finding goes; 04 keeps sections 1-5 and 7 (the container list is shaders.md's Containers by engine), and section 6 says where each kind of finding is. Facts in the old sections about one game only were checked against that game's note, where they already were. Statements the code no longer matches are marked as history beside the current value (movie output slots: MD_NOUT 64, MD_NOUT_AAC 32, MD_NOUT_VIDEO 16; APP_POOL is the profile key app_pool; Engage's layout is 5 / 4.375 GB; inline uniform updates are deferred by default; scaled copies are drawn), and Tears of the Kingdom joins the node-area entry's build list (issue #70). The game notes, docs/agents/README.md, 02 and 05 link to the exact entries, and so do the comments in nvn_mtl.m (nvnTextureCompare) and hle_audio.c (the RemoteIO buffer) and the provisional-profile note in profile_guess.py. 03 goes from 29,600 to 470 words, 04 from 34,400 to 3,500. Checked: every backticked span, module address, issue / PR number and 16-digit hash of AGENTS.md, development.md, dm/games/README.md and docs/agents/01-05 at 6a06877 (4,600 items) still appears in the repository's Markdown (the same five file patterns as before appear as the full names they stood for), every relative link and heading anchor in the repository's Markdown resolves, and the tool tests pass (the four that need capstone or lz4 in the T7 venv)

ROMANCE OF THE THREE KINGDOMS 8 REMAKE (0100C2A01A730000)

Update 1.1.3 (v851968) over the base game, with its four DLC. SDK 17.5.3 (Ace Attorney Investigations Collection's sdk and subsdk0 builds). Koei Tecmo's KTGL engine on NVN. Modules main, subsdk0 (the movie library, NintendoSDK_movie: the WebM logo and story movies) and sdk. Plays on the iPhone (IPA 16.8 GB); 30 fps, as on the Switch; controller only.

What it needs

Setting Where Why
4 GB layout: mem_reserve 0x100000000, mem_alias 0x10000000, mem_stack 0x10000000, app_pool 0xCD500000, sys_resource 0x0 game.tsv the NPDM declares no system resource (META +0x14 = 0): no virtual address memory; nninitStartup sets a heap of the pool − used memory (3.13 GB)
mem_used 0x5000000 (80 MB) game.tsv the rewritten modules take more than the default 64 MB, which SetHeapSize checks the request against
pad_layout full game.tsv the 3D gamepad layout: the dialogue boxes' auto and log buttons are the right stick and R3
Node area cut 1 GB → 62 MB dm/tools/sdk_patches.py, sdk build 311deab1… applies to this build by its ID; written for Ace Attorney Investigations Collection (010005501E68C000), whose virtual address memory needs it. This game has none

Display and input

  • The game draws 1280x720 into its 1920x1080 window textures and crops (WindowCrop), docked as well; a screenshot without DM_NVN_SHOT_OUT shows the whole texture, the picture in its top-left corner.
  • Controller only, with the 3D pad layout. main initializes the touch screen and gestures but never reads them (game.tsv: main imports no GetTouchScreenState); it reads a USB mouse (GetMouseStates), which the host does not provide. Touches as a mouse would suit it, but OCTOPATH TRAVELER 0, Tears of the Kingdom and Unicorn Overlord also read a mouse and no touch screen, so such a rule needs testing on them first.

Audio

  • Resolved: [RED] audren: a second renderer right after the first open, with the same work buffer and "original device 1 mode 1". Not a second renderer: SDK 17.5.3's OpenAudioRenderer with an event opens it by calling the form without one through the PLT (sdk+0x1e489c), which the loader binds to the host's hook, so ar_open ran twice for one renderer. The inner call started the render thread before the outer one had created the event, and the outer call took the renderer for a second one. A thread-local flag (t_in_open) now hands the inner call straight to the SDK with the host's CPU / manual copy of the parameter, and only the outer call starts the thread.

Files and shaders

  • A newer RDB than Age of Calamity's: 0002/root.rdb and 0002/system.rdb are the indexes (_DRK0000, with a .rdx beside each) over 296 0002/0x<KTID>.fdata files (12.2 GB) and 0002/data/0x<KTID>.file (and jaJP/, zhCN/ copies); game.tsv gives 12.6 GB for the RDB data. An .fdata starts with PDRK0000 and u64 0x10, then the same IDRK0000 entries (the u32 after the lengths is 1 or 0, the padding 16 bytes).
  • The compression is new: flag 0x400000 = chunks of u16 stored length, 8 bytes, then a zlib stream; with 0x100000 as well (flags 0x500000) the streams are LZ4 blocks. Each chunk inflates to at most 16 KB and a zero length ends. Of the 51,655 entries, 49,620 are LZ4, 2,026 zlib and 9 stored; all decode to the length in their header (shader_split.py idrk_data; 01).
  • Scenarios, messages, movies and their subtitles sit in loose folders beside the RDB.
  • The update is a multi-program patch: beside the game's patch (…0000, 1.5 GB) it carries a whole second program (0100C2A01A730001, 34 MB, a full NCA, not a patch) with its own Control NCA, which main starts with nn::oe::ExecuteProgram(1) (main+0xa31910). Resolved: nx_extract took the first Program NCA it found, the second program, and failed with NCA section 1 does not exist layering it over the base game; it now takes program index 0's NCAs. The host runs program 0 only (hle_oe.c logs the call).
  • Shaders: 59,363 GLSLC outputs (52,691 pixel, 5,359 vertex, 1,311 compute, 2 geometry): 59,214 in the G2S (_S2G5000 / 6000 / 7000) and _DOK0000 containers of the RDB entries, and 149 in main. The vertex shaders are single-stage programs, paired with a cover pixel shader. All build for the Mac (1 h 19 min on a 12-core M6).
  • Three shaders get textures of another type than they declare on some slots (texture type mismatch … bound as is, once each: a 2D array where a pixel shader declares 3D, cube and 3D textures where two vertex shaders declare 2D); nothing in the scenes below looks wrong.

Status on the Mac

  • From the logo movie and intro, the title and its attract demo, the main menu, a new game through the recommended setup (Ruler, Cao Cao, 195), its opening story on the map, the council (espionage, personnel, the help panel), a saved and loaded game, a month's missions, the city view, a visit and a practice duel in 3D.
  • 30 fps, as on the Switch (frame time p50 33.3 ms, p95 34.5 ms; GPU 5–7 ms a frame on the Mac in the duel), sound; about 2 GB resident in the council and 2.5 GB in the duel, flat on a screen left idle. The prewarm list covers that route.

Mac routes

  • The work folder's run/ctl.sh drives a run started with DM_CTL. From a fresh save: A (skips the intro), A at the title, A (New Game), A on Recommended, A ×3, the quiz's first answers (A, A, A), A on Ruler, X at Confirm Settings, A ×3 and X, then X at the story's Skip dialog: the council of 195 April, about 2 minutes.
  • run/save_ref holds a manual save there: A, A, Down, A (Load), A, X loads it.

Found on this game

General host changes first needed here; each applies to every game:

Open

  • Touches as a mouse: not done; it needs testing on the other games that read a mouse and no touch screen (above).
  • The three texture type mismatches above are bound as is.
