Return of the Obra Dinn

Update 1.0.1 (v65536), Unity 2017.4.28f1 IL2CPP with FMOD, SDK 8.2.0, NVN. Modules main, subsdk0 (NintendoSDK_movie), and sdk. No game-specific rewriter cuts or host rules.

What it needs

Files and shaders

• The update has 275 RomFS files, 1.98 GB, including 13 UnityFS bundles.
• All 122 Shader objects decode to their exact ends. The stripped 2017.4 layout matches the release type tree's 1,313 nodes and alignment flags.
• One stripped internalskinning ComputeShader object contains 12 kernels; all 67,416 bytes decode with the 2017.4 layout (120 nodes and alignment flags).
• 1,272 unique shaders: 633 vertex, 627 pixel, 12 compute. All compile for Mac and iOS. shader_pairs.tsv has one whole-program pair; pso_pairs.tsv supplies 611 supplemental pass-input cover pairs. The Mac prebuild links all 612 bases.

Mac validation

The title, save-slot menu, newspaper, opening letter, spoken introduction, rowing boat and ship's deck render correctly. A brief control check turns the camera, presses the interaction button and applies forward-stick input; deeper navigation was deliberately kept outside this check. No missing shaders, pipeline failures or other [RED] lines in the completed gameplay and light-play runs. Audio callbacks report no underruns.

The 30-second window at 80–110 seconds of light-play presents 1,799 frames (60.0 fps), with frame time p50 16.66 ms / p99 17.67 ms, GPU p50 6.37 ms, and no dropped presents. Direct presentation was used for this measurement (see Open). During the four-minute opening/deck run, resident memory settles around 1.22–1.24 GB after loading the scene; GPU allocation stays around 1.02–1.04 GB instead of growing each frame.

From a fresh save, DM_KEYS=10:A,12:A,18:A,21:A,24:A,27:A enters the opening; the boat is visible around 60 seconds. The short control check adds 65:RRight~1.4,67:RUp~0.4,70:A,72:LUp~1.5. Runs, timing TSVs and screenshots are in the NSP folder's 010032E00E6E2000-work/run/.

Found on this game

• Zero-guarded complemented jump-table index: the update's main+0x6eea88 and +0x6eeac0 have seven table entries, since the zero case branches away before complementing a three-bit index.
• Stripped Unity Shader layouts and ComputeShader objects: the 2017.4 layouts restore the engine resources and skinning kernels.
• Legacy Unity stages lose their pass partners: the separately selected stages have different blob indices; the pass's pixel inputs supply the padding that the OneBit/Rope pipelines need.

Open

• iPhone gameplay has not been tested.
• Later memories, the pocket watch and persistence across a story checkpoint have not been checked. The unsigned IPA is 908.7 MB; the Mac app is 2.1 GB.
• The base game 1.0.0 is not registered or validated by this profile. PR #427's base-game report is background evidence; this profile was rebuilt from 1.0.1.
• This Mac's display link repeatedly went silent during the first windowed run. Direct presentation (DM_PRESENT_LINK=0) isolates gameplay from that known Mac window issue; the profile keeps the normal presentation default.
