Hades (0100535012974000, update 1.0.38233, SDK 9) renders with Vulkan through The Forge, not NVN. The host now implements its 100 vk* imports on Metal in dm/gfx/vk/hle_vk.m, and the Vulkan loader (subsdk0) and NVIDIA's driver (subsdk1) are not loaded. The title menu, the intro and Tartarus gameplay run at 60 fps on the Mac, and a Metal validation run is clean. The iPhone build is untested. - dm/gfx/vk/hle_vk.m: one Tegra X1-shaped device. Memory is a lazily made shared MTLBuffer; images are private MTLTextures. Command buffers are recorded on the host and replayed at vkQueueSubmit on the layer's own queue, which signals an MTLSharedEvent. Descriptor sets, update templates, render passes and pipelines are supported. The swapchain presents through the NVN layer's present path. vkGet*ProcAddr look names up in the HLE table, also trying a name without its KHR suffix. - dm/gfx/tools/vk_shaders.py: SPIR-V to one metallib plus a slot table. It renumbers bindings per kind, flips vertex y, and lists only the resources the Metal entry point takes. - nvn_mtl.m/h: mtl_device, mtl_ext_tex and mtl_present_ext for external producers. Their present waits on the producer's event. - hle_nvn.c: dm_gfx_enter/leave and dm_vk_drain, so the background suspend also covers Vulkan submits. - hle_oe.c: GetNotificationMessageEvent returns a host-owned auto-clear SystemEvent. The SDK's version returned an event the no-op oe::Initialize never created. - patch_nso.py: the byte-table jump search looks 16 instructions back, not 8 (Hades main+0x1135d0). The output for every other module is byte-identical. - Profile key `graphics vulkan`: build_ipa.sh ships $MSL_IOS/vk instead of the NVN chain libraries. - dm/third_party/vulkan-headers: Vulkan-Headers 1.4.363, unmodified. - dm/.gitignore: per-game host binaries (dm/host/dmhost_*).

This is code written by others, shipped with the repository so there is nothing to download. Each component keeps its original license, and the license file sits in its own directory.

bcdec/ |
Decompression of BC-compressed textures, a single header bcdec.h |

flip/ |
NVIDIA FLIP, an image difference metric that models human viewing. FLIP.h plus the source of the command-line tool in tool/ |

libdeflate/ |
Decompression library | Upstream commit 92e6a0d, unmodified |
Host: zlib decoding of the game's resource blocks (dm/host/hle_tact.c). Only the five decompression-related source files are built; they are listed in dm/host/Makefile |

libvpx/ |
The VP9 decoder from libvpx: the 71 source files a VP9-decoder-only build compiles, their headers, and the generated configuration in config/ |
v1.17.0 (upstream commit 6df3ec3), unmodified |
Host: decodes the games' VP9 movies (dm/host/hle_movie.c). dm/host/Makefile builds it into gen/vpx/libvpx.a; the iOS build compiles the same files |

Ryujinx 1.3.2, unmodified | Referenced by the shader translation tool dm/gfx/tools/dmsh_xlate, which translates the original Switch shaders to SPIR-V |
ryujinx/LICENSE.txt (MIT); ryujinx/src/Spv.Generator/LICENSE is that subproject's own license text |
vulkan-headers/ |

A few more notes:
flip/tool/also carries three single-header libraries used by the FLIP command-line tool:stb_image.h(2.23),stb_image_write.h(1.13) andtinyexr.h. Their license notices are in the files themselves.bcdec/README.md,libdeflate/VERSION.md,libvpx/README.md,stb_vorbis/README.md,ryujinx/README.mdandvulkan-headers/README.mdrecord where each came from and what it is used for.- Two pieces of third-party code live outside this directory:
dm/gfx/nvn/include/nvn.h(MIT, author named in the file header) and the layout size algorithm indm/gfx/nvn/nvn_tex.c, ported from deko3d (zlib license).
