Profile 010057D006492000 (no virtual address memory: the 4 GB heap layout; tex_flush_upload and tex_dirty_upload for the textures Unreal writes from the CPU into uncached pools after creating them) and its note. Brought up on the Mac through the boot, the language notice, the title, the traveler selection and Ophilia's and H'aanit's openings (free play in the cathedral and in S'warkii) at 30 fps; battles, sound and the iPhone not yet tested. General changes found on it: - patch_nso.py: a jump table whose index is bounds-checked with a 64-bit cmp (main+0x1676f58), accepted only in the last pass so earlier rewrites are byte-identical. - profile_guess.py: Unreal's 64 GB alias layout only with virtual address memory (this game sets a 3.08 GB heap instead). - NVN: nvnTextureBuilderGetSparseTileLayout / nvnTextureGetSparseTileLayout (Unreal sizes a sparse texture's mip tail with it; unimplemented, it asked for 1.75 GB twice); sparse 2D textures without a packaged layout take the block height of their 64 KB tile (the world map's tiles were shuffled); every virtual pool gets an address range of its own until its first mapping decides between the alias (a whole-pool mapping, Mario's pool) and the sparse page table (Unreal's one-texture pools, mapped piece by piece: streamed textures were black and later mappings refused). - Audio renderer: SdkMutexType is looked up only when the SDK uses it (SDK 3.5.1 takes LockMutex at +0x1f8). README: the gallery entry (Mac screenshot of S'warkii, IPA ~3.6 GB, all 5,434 shaders built for iOS); AGENTS.md: seventy-one games. Checked on the rebased tree: the tool tests (15 skipped), the docs tests, a Mac boot into the traveler selection; before the rebase the graphics tests (make run, exit 0).

# Bayonetta 2 (`01007960049A0000`)
|
||
|
||
Update 1.2 (`v131072`) over the base game, SDK 3.6.0 (no other game's `sdk` build), the oldest SDK until [OCTOPATH TRAVELER](../010057D006492000/README.md)'s 3.5.1. PlatinumGames' own engine in its Wii U form (not [Bayonetta 3](../01004A4010FEA000/README.md)'s) on NVN. Modules `main`, `subsdk0` (NVN's GLSLC: `main` imports `glslcCompile` but did not call it on the route below) and `sdk`. Wwise sound through two 6-channel `AudioOut`s; CRI's file system (CPK) and Sofdec movies (USM), both decoded by the game's own code. Plays on the iPhone (IPA 12.5 GB). [Bayonetta](../010076F0049A2000/README.md) runs on the same `sdk` and `subsdk0` builds.
|

|
||
On the Mac: the boot, the PlatinumGames logo movie (USM), the title, a new game (slot 1, the auto-save notice, Story, Normal), the opening narration (The Legend of Aesir, which cannot be skipped on a first play), the prologue's cutscene (skipped: Plus, Down, A, A), the tutorial (closed: Plus, Down ×4, A), Verse 1 on the jet, Rodin's cutscene and the next fight with an Umbran Climax and a torture attack, with sound. 60 fps in play (frame time p50 16.67 ms, p95 about 17.5 ms; GPU 2–3.5 ms a frame on an M6), 30 in its cutscenes as the game asks; about 1.6 GB resident and 1.75 GB of Metal allocations. The title is up about 20 s after launch.

||
## What it needs
|
||
|
||
| Setting | Where | Why |
|
||
|---|---|---|
|
||
| 4 GB layout: `mem_reserve 0x100000000`, `mem_alias 0x10000000`, `mem_stack 0x10000000`, `app_pool 0xCD500000` | [`game.tsv`](game.tsv) | the 4 GB block of the other games without virtual address memory (256 MB in front + 256 MB alias region + 256 MB stack region + 3.25 GB heap region) |
|
||
| `sys_resource 0x0` | `game.tsv` | the NPDM declares no system resource (META +0x14 = 0), so there is no virtual address memory: `nninitStartup` sets a heap of the pool − used memory (3.11 GB) |
|
||
| `mem_used 0x6600000` | `game.tsv` | the rewritten modules (102 MB) are larger than the default 64 MB of used memory, and the game's `SetHeapSize` asks for pool − used |
|
||
| `pad_layout full` | `game.tsv` | the 3D pad layout: the camera is on the right stick. The game also offers touch controls in handheld mode; the profile keeps it docked |
|
||
| `shader_groups /shadereff.dat/=eff /shader=core` | `game.tsv` | the shaders of the effect DAT and of the other shader DATs |
|
||
| `zip_store .cpk:.usm:.metallib` | `game.tsv` | already-compressed files stored as they are in the IPA |
|
||
|
||
## Files and shaders
|
||
|
||
- Six CRI CPK archives in the RomFS root (`data000.cpk` … `data006.cpk`, there is no `data004.cpk`; 9.5 GB, 6,091 files, 12 GB of them CRILAYLA-compressed) of PlatinumGames DAT archives, beside the USM movies (`movie/`) and the Wwise sound (`sound/`). The CPK layout is in [01](../../../docs/agents/01-extract.md); `dm/gfx/tools/cpk.py` reads it.
|
||
- **Current:** 1,856 BNSH files of one stage each (1,547 pixel, 309 vertex), the `.vso` / `.pso` members of `shader.dat`, `shader2.dat` and `shadereff.dat` in `data000.cpk`. The split decodes every CPK entry (`shader_split.py` `cpk_jobs`, about 2.5 minutes). All build for the Mac and iOS.
|
||
- A prewarm list recorded on the Mac over the route above (974 lines).

||
## Rendering
|
||
|
||
- **Resolved: the opening narration drew in a corner of a black screen.** Every frame starts with a pass whose colour target is 32x32 (then 256x256 ones) beside the 1280x720 depth buffer, and the game clears the depth there; the host cleared only that corner. The earlier opening scenes had speckled and blocky patches, and a full-screen grain overlay showed one tile. Fixed generally ([Clears of attachments larger than the render pass](../../../docs/reference/rendering.md#clears-of-attachments-larger-than-the-render-pass)).
|
||
- **Resolved: the bloom chain** (`[RED] Downsample case not implemented: 320x176 1 samples format 70 → 80x48`): `nvnCommandBufferDownsample` from a 320x176 target into 80x48 and 48x32 textures, and from the 1280x720 BGRA8 frame into an RGBA8 texture ([`Downsample` of a single-sample texture](../../../docs/reference/rendering.md#downsample-of-a-single-sample-texture)).
|
||
|
||
## Mac input
|
||
|
||
The work folder's `run/route.sh <run> [secs]` boots on a fresh save and presses A five times from the title (slot 1, the notice, Story, Normal); `run/ctl.sh` / `run/step.sh` press and take shots, `run/watch.sh` takes a series of shots, and `run/fight.sh` repeats a simple combo. `run/save_ref` holds the save after Verse 1, `run/save_ref2` the one after the second fight.

## Found on this game
|
||
|
||
- **SDK 3.6.0 answered as SDK 4**, with no host change for the SDK itself: [services.md](../../../docs/reference/services.md#sdk-360-answered-as-sdk-4).
|
||
- **CRI CPK archives and the BNSH files in their DAT archives** (`cpk.py`, `cpk_jobs`): [shaders.md](../../../docs/reference/shaders.md#bnsh-files-in-platinumgames-dat-archives-inside-cri-cpk-archives).
|
||
- **A cleared attachment larger than the render pass is cleared in a pass of its own** (`rp_begin_ex_`): [rendering.md](../../../docs/reference/rendering.md#clears-of-attachments-larger-than-the-render-pass).
|
||
- **`Downsample` of a single-sample texture as a filtered scaling copy** (`copy_t2t`): [rendering.md](../../../docs/reference/rendering.md#downsample-of-a-single-sample-texture).
|
||
|
||
## Open
|
||
|
||
- Not checked: 13 Sentinels and Catherine: Full Body's CPKs with the new reader (no files on the drives), and the clear fix in other games beyond the unit tests.
|
||
- AGENTS.md still calls Mario Kart 8 Deluxe's SDK 4.4.0 "the oldest SDK so far"; this game's SDK 3.6.0 is older.
