oboromi

a WIP ounce emulator foundation written in Rust

written lowercase.

oboromi is a WIP emulator for the Nintendo Switch 2.

It currently emulates an 8-core ARMv8 CPU with 12GB of shared memory and a SM86 (NVIDIA Ampere) stub GPU.

It can't run any commercial games nor firmware at this stage.

• core: core lib.
  • audio
  • fs: filesystem VFS
    • probably would emulate a 32 GB UFS/eMMC to start with
  • gpu: Ampere SM86 GPU emulation/recompilation
    • sass to spirv conversion
    • transliteration into vulkan, constants and register map
  • nn: HLE emulation of firmware
  • sys: entire emulation state
  • tests
• docs
  • sm86.pdf: autogenerated sm86 instruction set document with nice coloured table diagrams :^)
• gui: simple eframe based UI for debugging
• scripts: misc. helper/autogenrators
  • decoder_generator.rs: generates parser stuff from sm86 descriptions
  • sm_86_instructions.txt: instruction dump, sourced from DocumentSASS.
  • sm_86_latencies.txt: instruction latencies as well, sourced from DocumentSASS.
