Preserving the Arcade Soundscape: A High-Level Emulation Approach for the Capcom QSound DSP Architecture Saki Sasaki Endless Pleasure For This Body A Upd Apr 2026
The preservation of arcade audio hardware presents unique challenges distinct from video or CPU emulation. The Capcom QSound system, introduced in the early 1990s, utilized a proprietary DSP to simulate 3D spatial audio. Low-level emulation (LLE) of this chip requires substantial computational resources due to the complexity of bit-perfect DSP cycle timing. This paper proposes a High-Level Emulation (HLE) methodology for the QSound architecture. By decoupling the emulation from cycle-accurate DSP simulation and instead utilizing static recompilation of sound ROMs and high-level audio processing routines, we achieve significant performance gains while maintaining the spatial characteristics essential to the original hardware’s output. The Capcom Play System (CPS) series defined the 2D fighting game genre throughout the 1990s. While the CPU and graphics hardware have been successfully preserved through low-level emulation, the audio subsystem—specifically the QSound processor—remains a bottleneck for cycle-accurate performance on low-power devices.

The QSound system, developed by QSound Labs, Inc., provides stereo audio with positional 3D effects. In original hardware, a dedicated Z80 CPU manages the sequencing, while a custom QSound DSP handles the audio synthesis and spatial processing. The firmware for this DSP is contained within a specific ROM file, colloquially known in emulation circles as qsound_hle.zip or qsound.zip .
