Qsound-hle.zip — Rom ^new^
If you are getting errors about missing files or have no sound in Capcom games:
If you've been firing up a newer version of MAME and noticed some of your favorite Capcom games are missing their iconic "QSound" audio, you've likely run into a missing qsound_hle.zip
At its heart, the QSound chip is a with a mask-programmed ROM . Its design allowed it to perform complex spatialization effects, making the game's audio feel wider and more directional than its simple stereo output would suggest. This technology became a staple in many of Capcom’s most famous arcade hardware platforms, including the CP System II (CPS-2) , CP System Dash (CPS-1) , and even the ZN-1 and ZN-2 platforms. qsound-hle.zip rom

As one MAME developer noted in a commit at the time, the change involved improving the qsound_hle core to use ROM lookups and enums for most DSP ROM addresses. If you are getting errors about missing files
For years, arcade emulators like older versions of MAME used . They required a file containing the original QSound DSP program. That file was historically named qsound.bin or qsound.zip . However, these original DSP dumps were often problematic. Some were corrupt, others were copyrighted firmware that legal purists wanted to avoid distributing, and many failed to initialize correctly on certain game revisions.
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.

| Feature | High-Level Emulation (HLE) | Low-Level Emulation (LLE) | | :--- | :--- | :--- | | | Simulates the response of the audio system, reimplementing its functions at a higher level. | Mimics the internal design of the hardware, faithfully recreating each component's behavior at a low level. | | Primary Goal | Maximize performance and speed, often at the cost of some accuracy. | Achieve the highest possible accuracy, even if it requires more processing power. | | Performance | Highly efficient, ideal for weaker hardware like retro handhelds or the Raspberry Pi. | More resource-intensive, requiring a powerful CPU for full-speed emulation. | | Accuracy | Sound may be "good enough" but can lack subtle nuances or have minor glitches. | As close as possible to the original arcade hardware, often considered "perfect" emulation. | | File Purpose | qsound-hle.zip provides the HLE implementation, allowing for fast and efficient audio emulation on a wide range of devices. | LLE would require a dump of the actual QSound DSP-ROM, but no known game uses this second, more accurate, mode. |
