The record

Product: SnesFox is a Super NES emulator that runs SNES ROMs, including Super FX (GSU) games such as Star Fox.
Debug interface: Its debug view shows CPU, PPU, APU, and GSU state, an instruction log, playback controls, a palette editor, a VRAM tile viewer, and a GSU work-RAM viewer for Super FX games.
ROM tools: The command-line tools can inspect ROM headers, capture PPU/VRAM snapshots, disassemble ROMs, reassemble supported dumps, and record execution coverage.
Super FX: The emulator supports Super FX (GSU) games and includes GSU state panels and a work-RAM viewer in its debug UI.
Window modes: SnesFox offers a bare game-only window and a debug UI mode, and the bare window supports resizing and fullscreen.
macOS build: The documented macOS build uses clang++, Xcode Command Line Tools, and SDL2; Dear ImGui is vendored in the repository.
Windows build: The documented Windows executable is cross-compiled from macOS or Linux with mingw-w64, and the repository says there is no native Windows toolchain path.
Linux limitation: The README says there is no Linux build path yet, though Linux can be used as a host to cross-compile the Windows executable.
Testing: An in-binary self-test runs CPU, PPU, and S-DSP regression tests without requiring a ROM.
Coverage limitation: Execution coverage records what the emulator executed in a particular run and may not represent every path in a game.
License: The repository lists an MIT license.
Availability: The GitHub repository is public and its Releases page shows no listed release entries.
Purpose: SnesFox is a Super NES emulator for running game ROMs, including Super FX (GSU) titles such as Star Fox.
Graphics tools: The debug UI includes editable CGRAM palette swatches and a full-VRAM tile viewer, plus a GSU work-RAM viewer for Super FX titles.
