Description
A WebAssembly emulator built on a patched Unicorn engine that executes supplied firmware against a modeled board: all 64 pads, the other buttons, six encoders, LEDs and the display. It can load images from the community registry after checking their SHA-256, run UI scripts, validate an image against the specification, and connect to a physical SQ-64 over Web MIDI for firmware transfer (update mode) and backup and restore (normal mode). The authors describe the board model as experimental, not a hardware certification; analog outputs and electrical timing are outside its evidence. No Korg firmware is included.
