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)

Stardew Valley (0100E65002BB8000)

Update 1.6.15.13 (v1310720; the base game v0 is not extracted), SDK 20.5.27. MonoGame for the Switch, as Celeste (01002B30028F6000): MonoGame's and the game's C# compiled to C++ by Sickhead's BRUTE into main (124 MB of code, 230 MB with its data and bss) with a Boehm collector; XACT sound (Content/XACT, 0.48 GB of wave banks) through the audio renderer; NVN. Modules main and sdk only. It links Pia and NPLN for online co-op and LDN for local co-op. Plays on the iPhone (IPA 0.6 GB); no host change in this profile's change.

Status on the Mac

  • The title, a new farm (character creation with the software keyboard, Skip Intro), the farmhouse, the farm and its tools, the bus stop, Pelican Town by day and night (lamp light), Pierre's shop and a purchase, the game menu, the mail, a night's sleep and its save, Load from the title, and the Co-op menu (Online Communication goes back to the title with no network). No red line on that route.
  • 60 fps: frame time p50 16.67 ms, p95 16.8 ms; GPU about 0.6 ms a frame on an M6; CPU 8% of a core, 0.27 W. Sound.
  • 0.46 GB resident at the title and 0.93 GB in play, flat over the last 10 of 23 minutes; 0.3 GB of Metal allocations.
  • The title is up about 20 s after launch.

What it needs

The provisional profile's guesses held.

Setting Where Why
sys_resource 0x0 game.tsv the NPDM declares no system resource, so IsVirtualAddressMemoryEnabled is false, as on Horizon: no virtual address memory. The game sets a 2.96 GB heap (pool − used memory)
4 GB layout: mem_reserve 0x100000000, mem_alias 0x10000000, mem_stack 0x10000000, app_pool 0xCD500000 game.tsv 256 MB in front + 256 MB alias region + 256 MB stack region + 3.25 GB heap region
mem_used 0xda5c000 (218 MB) game.tsv the rewritten modules are larger than the default 64 MB of used memory (214 MB without main's 29.6 MB of bss, + 4 MB: profile_guess.py mem_used), so the heap request plus the modules would exceed the pool
pad_layout full game.tsv the 3D layout: the D-pad for menus and the right stick for the cursor
shader_groups /Content/=content game.tsv the MonoGame effects; see Files and shaders

Files and shaders

  • 3,549 XNB files, 3,535 of them LZ4 and 8 LZX (MonoGame's compressed XNB; LZX is flag 0x80, LZ4 flag 0x40).
  • Current: 65 shaders (23 pixel, 42 vertex): 64 in the MonoGame effects in main (SpriteBatch's and the game's) and one in Content/Effects/ShadowRemove.xnb, an LZ4 XNB that shader_split.py decompresses before reading it (xnb_decompress).
  • Nearly everything draws with SpriteBatch: the prewarm list is its two shaders and four pipelines, and with it nothing was built on demand over the route above.

Input

  • The pad only (main imports no touch screen or mouse). The D-pad moves between menu items, the right stick moves the cursor, ZL / ZR change the toolbar slot (empty slots are skipped), X opens the menu, Y uses the tool, A checks.
  • The game drops presses while a menu fades in or out (about a second after it opens or closes).
  • Resolved (PR #120): the Mac text box. Character creation names the farmer and the farm through the software keyboard, and it re-opened the keyboard after every OK. The Mac text box (front_mac.m) now releases the buttons that opened it, and stays up while the text is shorter than the minimum length.

Mac routes

  • The work folder's run_v/boot.sh <log> [secs] VAR=… runs build/valleyhost (SV=<save dir> for a copy of run_v/save_ref, the morning of day 2 in the farmhouse); run_v/ctl.sh drives a run started with DM_CTL; run_v/step.sh <shot> [wait] <presses…> presses and takes a screenshot.
  • The title is up about 20 s into a boot: A (Load) and, a second later, A (the save).
  • Menu presses held 0.3 s or more repeat, so hold 0.2 s. Walking takes the left stick (LLeft~1.3 is about five tiles).
  • In character creation with DM_KBD=<text>, A on each of the three text boxes fills it, and Skip Intro is the last item above OK.
  • Out of the farmhouse (its door is below the gift box), the path east above the weeds, past the mailbox, leads to the bus stop, and east from there to Pelican Town.

Found on this game

General host changes first needed here (PR #120, before this profile's change); each applies to every game:

  • Compressed XNB decompressed before the MGFX reader (xnb_decompress in shader_split.py): MGFX effects in MonoGame XNB files.
  • The Mac software keyboard's text box releases the buttons that opened it and stays up below the minimum length (front_mac.m): described in Input above.
  • Spin waits through stores (patch_nso.py "Spin waits"): one more loop in this game's main: development.md, Power.

Open

  • About one frame in 800 takes 24–47 ms (nine in two idle minutes in the farmhouse): game CPU time, with no pipeline build, upload or present in it, while the main thread otherwise sleeps 95% of each frame in SleepThread (sampled), whose host sleep is exact. Probably BRUTE's Boehm collector; not checked further.
