Pulsar II: reconstructing Linux support from Windows SCOPE analysis

The Pulsar II project reconstructs Linux support for the Creamware/Sonic Core DSP sound card from analysis of scScope.sys and Sim2k.dll. Its kernel module, loader, and SCOPE file decoders handle card initialization, DSP modules, audio streams, and device files; reports document register and boot behavior.

Requirements & limits

Prerequisites: A Creamware/Sonic Core Pulsar II card and Linux kernel headers for the driver.
Prerequisites: The official SCOPE 5.1 installer and a valid licence are needed for DSP files, which are supplied by the user.
Limits: External clock and factory synth, ADAT, S/PDIF, and MIDI port support remain incomplete or untested.
License: GPL-2.0-or-later for the driver and tools; the MAME-derived SHARC disassembler remains BSD-3-Clause.
