Blasphemous

Update 1.0.8 (v524288) over the base game, SDK 8.3.1, Unity 2017.4.28f1 IL2CPP with FMOD on NVN. Modules main, subsdk0 (NintendoSDK_movie) and sdk. Plays on the Mac: title, patch notes, new game, opening H.264 cinematic, awakening, healing, movement, jumping and a sword swing in the first room. Gameplay testing deliberately stops there. iPhone/iPad validation remains open.

What it needs

No game-specific rewriter cut or host change. The general forward-initialized jump-table fix below is required to rewrite main.

Files and shaders

• The merged RomFS has 4,417 files, 6.07 GiB, including 99 UnityFS bundles, the player's serialized assets, 13 MP4 movies and FMOD banks.
• The DLC NSP is a licence-only package, index 1 (0100698009C6F001); packing recognizes the licence. Its content was not separately tested.
• 617 shaders: 304 vertex, 301 pixel and 12 compute. Four GLSLC outputs are in main; the other 613 come from Unity assets. All compile on the Mac, with zero unresolved bindings or unfillable driver-bank reads.
• The legacy Unity supplemental pairs plus the serialized pair give 309 pipeline bases; all 309 prebuild successfully. pso_manifest.tsv records the checked opening route's 43 unique shader/pipeline entries.
• All 617 shader libraries compile for iOS too. The unsigned IPA is about 0.9 GB (877.5 MiB), built for user sideloading; device runtime validation remains open.

Performance and validation

• Tested on the Mac on 2026-10-28, in a five-minute startup and opening-room run. No runtime [RED] message, abort or crash. The process was stopped after the short control check.
• The first room presents at the game's 60 fps target. Settled 300-frame windows report frame-time p50 about 16.67 ms and GPU p50 about 0.8–1.7 ms. Other builds were active, so these are diagnostic observations rather than an isolated benchmark.
• Resident memory settles around 1,936–1,938 MB in the opening room, with Metal allocations around 2,054–2,055 MB; no sustained growth in the checked interval. This is a brief check, not a long-session leak test.
• FMOD opens one AudioOut. Settled callback windows report zero underruns. The movie module produces visible H.264 pictures and subtitles.
• The Python tool suite and make -C dm/gfx/tests GAME=0100698009C6E000 run pass. The rewriter's new fallback has synthetic tests for bounds, base clobbers, incoming branches, invalid targets and table extent. The IPA passes unzip -tq; its six shipped profile tables match the repository copies.
• regress.py check --quick checked Return of the Obra Dinn (the closest Unity 2017.4 compiler) and Super Mario Bros. Wonder (an established x18 rewrite route). Two games are sufficient for this narrow fallback: every previously recognized site takes its old path, and all five rewritten modules of these games are byte-identical to the baseline. All 17,540 shader outputs and pipeline interfaces are unchanged; both routes reach their frame targets with zero new [RED] kinds. Wonder reports PASS. Obra Dinn reports REGRESSION for FPS 59.8 → 53.4 in the measured window; both runs are marked busy with concurrent jobs, so the performance comparison is inconclusive. Its screenshot changes (RGB 8.5 and 7.97) show a different rowing-animation phase on visual review. The earlier full Obra Dinn run measured 59.9 → 59.1 fps with no runtime errors. The final report is in the NSP work folder's regress-quick-report/report.md; other games were not checked.

Mac route

Build with scripts/build_ipa_from_nsp.py <NSP folder> -k <prod.keys> --platform mac and use its printed command. At the title press A, dismiss the first-run patch notes with B, press A on Pilgrimage, then A on the first empty slot. Let the opening advance; B can skip a cinematic segment when enabled.

The opening room initially requires L to heal before movement is available. Dismiss the Biliary Flasks tutorial with B. Left stick moves, B jumps and Y swings the sword. The default 2D touch-pad layout exposes these controls.

The checked route used a windowless diagnostic run (DM_PRESENT_LINK=0, omit DM_WINDOW) with audio and DM_CTL screenshots. The save contains the first new-game slot; save reload was not tested.

smoke.tsv is a short fresh-save title-screen route, without input or gameplay. A second 40-second boot checked the registered profile and final rewritten modules.

Found on this game

• Offset table base initialized after the dispatch: the general rewriter fix, found at main+0xae95f8.
• Existing Unity 2017.4 shader containers and Unity video planes work without another change.

Open

• iPhone/iPad runtime validation, save reload, combat encounters, bosses, later areas and DLC content. The base version was inspected for build lookup but was not played or registered.
• An isolated repeat of the noisy Obra Dinn performance comparison above; no claim of an existing-game performance improvement or regression follows from these busy-Mac timings.
