A PS5 homebrew port of RBDOOM-3-BFG (Robert Beckebans), title PPSA99313, running at 3840x2160 on Vulkan through RADV with the BFG Edition's data. - The engine as a submodule at upstream ea29c006, with the console's changes as ps5/patches/rbdoom3bfg.patch: Vulkan from RADV's entry point, title paths, start-up arguments (gamepad on, no log), a restart through the system, a pad opened when it arrives late, and PS5 frame timings (com_ps5Speeds). - SDL2 with the console's video, audio and pad drivers; openal-soft on SDL2. - Shaders compiled ahead of time with ShaderMake and DXC (built from source for an arm64 host); the ISPC kernel compiled on macOS. - A material fix for the flashlight beam's dust, title art, README and licensing notes.

# Doom 3 BFG for the PlayStation 5 - RBDoom3BFG's ISPC kernel, as an x86-64 object.

# ps5/tools/ispc-kernel.sh on macOS: build/ispc/kernel.o and kernel_ispc.h

|
# RBDoom3BFG's BC6H encoder (neo/libs/ispc_texcomp, used when it loads baked
|
|
# lighting) is ISPC source. ISPC's arm64 Linux release has no x86 backend, so
|
|
# the VM cannot compile it; its macOS release can. tools/vm.sh build runs this
|
|
# on the Mac first, and the title's build links the object it leaves
|
|
# (ISPC_PREBUILT_DIR, ps5/patches/rbdoom3bfg.patch), with upstream's own
|
|
# target (SSE4, x86-64, position independent).
