What and why

A profile for Kirby and the Forgotten Land – Nintendo Switch 2 Edition + Star-Crossed World: program 1 (04004D300C5AE001) of the application 01004D300C5AE000, update v65536 (1.1.0), SDK 19.3.7 built for the Switch 2 (Ounce), NVN2. The Switch 1 game keeps its own profile: the Edition has another executable and other shaders.

What it adds (dm/games/04004D300C5AE001/):

• game.tsv:

  • The memory layout: a 5 GB block with a 4.375 GB alias region, and the Switch 2's 9 GB pool. The NPDM declares 16 MB of system resource and main never sets a heap.
  • The modules and the shader groups.
  • depth_mode zero: the game calls nvnDeviceSetDepthMode with near = 0 at boot.

  These are as the NSP script's survey and address-region check found them.

• The shader split's tables: 93,348 shaders. 93,343 translate on the current chain. 5 do not: they use one form of Ampere instruction 0x80d that the translator only knows as the guard band cull.

• A prewarm seed list (pso_manifest.tsv) recorded in play: 9,202 shaders, 1,712 render pipelines and 16 compute pipelines. Every shader key is in the shader map.

• The game note and its row in the games table.

Depends on:

• #1639, to pack and run a raw dump's program 1. Main cannot pack this program yet.
• #2548, the nn::pl::GetBuiltInFontDataSet takeover, which the game calls at boot.

The README's Switch 2 list is left alone until the game can be packed from main.

Checked

• Tests: these pass on this branch:
  • make -C dm/host game_profile GAME=04004D300C5AE001: the header generates.
  • dm/tools/tests/test_docs.py
  • test_game_profile.py
  • test_architecture.py, test_issue_areas.py
  • test_nro_graphics.py, test_nso_match.py
  • test_nsp_aarch64.py, test_nsp_alias.py, test_nsp_incremental.py
  • test_profile_guess.py
• Games run: Kirby and the Forgotten Land – Nintendo Switch 2 Edition (04004D300C5AE001, v65536). About 9.5 minutes of play from boot (34,200 frames) at 60 fps, with no crash or abort.
  • Frame time: p50 16.66 ms, p95 16.85 ms.
  • CPU: 4.78 W.
• What it ran on: a build of Super Mario Bros. Wonder Nintendo Switch 2 Edition (Program 1): boot, New Game, Continue and correct rendering on the Mac #1639's branch, with host/pl: take over GetBuiltInFontDataSet for Switch 2 font types #2548 and two fixes to that branch against current main:
  • nn::pl::RequestLoadNxFont is taken over once. Main's takeover and the branch's both registered it, and the loader aborts on a duplicate.
  • The damaged-file check reads a raw dump's RomFS folder, which has no RomFS.img.
• Not run on this branch itself: main cannot pack program 1 without Super Mario Bros. Wonder Nintendo Switch 2 Edition (Program 1): boot, New Game, Continue and correct rendering on the Mac #1639.
• Devices and OS: MacBook Pro M4 Pro, macOS 27.2.1.
• Regression check: none run. This is a profile and its note only, and no host, chain or tool code changes.

Open (in the note):

• Two shaders fail to load at run time.
• About 30 [RED] texture type mismatch lines, where a 2D array is bound to a 2D slot.
• The [RED] more than 16 font engines lines.
• The rest of the game, iOS and the Star-Crossed World content are untested.

Docs

• The finding is in its game note, and python3 dm/tools/docs_symptoms.py was run (symptoms.md unchanged)
• A chain tool changed: not applicable
• No game files, keys or data extracted from a game in the change or the attachments. The tables hold shader keys, offsets and pipeline keys, as other profiles' do.
