The Legend of Zelda: Echoes of Wisdom (01008CF01BAAC000)
Update 1.1.0 (v196608) over the base game, SDK 20.5.1, NintendoWare G3d / Ui2d / Vfx / Atk / Font on NVN. Modules main, subsdk0 (GLSLC), subsdk1 (NintendoSDK_movie) and sdk.
Status
Playable on the Mac: title movie and logo, file selection, the opening autosave and its reload, and Link's opening Suthorn Ruins corridor through the raised door, rubble jump and upper hall. Movement, jumping, sword input and the right-stick camera work. Both Mac and iOS shader builds produce all 9,858 libraries with no unresolved bindings. An unsigned IPA was built (about 7.8 GB); iOS gameplay remains untested.

No game-specific rewriter cuts, SDK cuts or host branches are needed for the tested route. Only update 1.1.0 is registered; the base build has not been brought up.
Rendering and shaders
- Current: lower-left window origin and near-zero depth, both selected from the game's NVN calls. The existing host handling used by Link's Awakening applies.
- Resolved: a false red cube/2D warning at the first raised-door transition. The particle fragment shader
aca252efc381a89d(region_common/effect/Common.ptcl, BNSH at0x59bc000, variation 3868) chooses reflection cube slot 14 only when the first integer in uniform slot 13 is positive; otherwise it samples cube slot 13. The captured failing draw has that integer equal to zero and a valid 64×64 cube in slot 13. Slot 14 retains a 1408×792 2D depth-stencil texture (ID 272), so it is unused by this draw. The NVN descriptor itself is 2D: no cube view was lost. The existing zero-cube binding is valid; reporting the binding as a rendering error was wrong. Its general handling now reports an informational fallback. The particle shader and rendered output require no workaround. - Warning validation: the isolated replay first reproduced the red line in 52.6 s; tracing captured the conditional input and selector. After the fix, the same fallback and the following room render without red lines (63.3 s through frame 3600). The GPU regression has 42 checks under Metal API validation: all pass, versus six false diagnostic failures before the fix. Reproduction scripts, isolated saves, logs and the room screenshot remain under the game's work folder in
cube-repro/. The unsigned IPA was rebuilt with the fix. - 9,858 unique shaders: 5,268 vertex, 4,553 pixel and 37 compute; 7,495 variation pairs. The split finds 9,818 in RomFS containers and 40 in
main. No unbuilt shader and no undecoded binding in the full Mac build. - Current: 281 prewarm entries in
pso_manifest.tsv, recorded through the title, menus, save reload and opening corridor. The final Mac check loaded 144 shaders, 129 render pipelines and eight compute pipelines in 0.37 s of background work, with no unmatched shader keys. - Files: models and maps in
region_common/actorandregion_common/map, shared BNTX textures inregion_common/sharedtexture, 96.bfshaarchives underregion_common/shader, six.ptcleffect files, and SARC.arcUI archives. Nineteen WebM movies; NintendoWare sound inregion_common/audio/edward.bfsarand.bfstmstreams.
Audio and memory
- Current: the SDK audio renderer runs at 48 kHz, 240 samples per frame, 96 voices and a six-input DeviceSink. The Mac callback reports non-silent output and no underruns in the tested route.
- The first dungeon corridor settles around 1.7–1.8 GB resident with 1.3 GB allocated by Metal. Level transitions change the footprint; the seven-minute repeat ends at 1,831 MB resident / 1,261 MB Metal, with a stable 490-pool count and no continuing growth in the stationary corridor windows.
- The corridor runs at the game's 60 fps when the Mac window is presenting. First-use pipeline compilation causes hitches. Window-inactive timing is not a gameplay frame-rate measurement.
- Validation: four-minute and seven-minute repeats through the opening corridor, followed by an 85-second run of the finalized profile with prewarming enabled. The final run has no red line. Timed runs end deliberately with SIGALRM (
CRASH sig=14), rather than a game crash. The unsigned IPA's ZIP CRC check passed; it contains all 9,858 base shader libraries and no signing entries.
Mac routes
The development build is 01008CF01BAAC000_build/ beside the NSPs, with runs and diagnostic saves in 01008CF01BAAC000-work/run/. Set DM_ROMFS to the build's extract/v196608/RomFS, DM_MSL_DIR to shader/cache, and DM_NVN_SHMAP to this profile's shader_map.tsv.
- A fresh save starts the opening prologue and creates File 1's Suthorn Ruins autosave. Subsequent starts show the title.
- From that save,
DM_KEYS="f600:L+R~0.5,f720:A,f840:A,f960:Up,f1080:A"selects File 1, the autosave, then Yes (the confirmation initially selects No). - In the opening corridor,
LUp~5reaches the first raised door platform;LUp+B~1.2jumps onto it and triggers the opening. In the next room, jump over the low rubble with B, then walk up the stairs. The right stick rotates the view; Y swings the sword. DM_CTL=<file>accepts live inputs andshot <absolute PNG path>as described in debugging.
Open
- Later gameplay and iOS runtime validation remain open.
Found on this game
- Unused conditional cube inputs are not rendering errors: A 2D texture in a cube slot binds the zero cube.
