Place the qsound-hle.zip file (do not unzip it) directly into your roms folder, alongside the CPS-2 game zip files (e.g., sf2ce.zip ).
For many years, the qsound.zip file was the magic key to getting games like Street Fighter II Turbo , Alien vs. Predator , and Dungeons & Dragons: Tower of Doom to produce sound. However, starting around MAME 0.201, this changed. Enter .
: Most CPS-2 games (like X-Men vs. Street Fighter ) are "parented" to the QSound device.
Unlike a direct, cycle-accurate simulation (Low-Level Emulation or LLE) of the DSP16A processor on the sound chip, the approach emulates the sound chip's behavior at a higher level, which is faster and often more stable for emulation. Why is it Needed in MAME?
The QSound chip (formally labeled DL-1425) was used extensively in Capcom’s CP System II hardware. It was a specialized digital signal processor (DSP) that allowed for high-quality audio, including 16 PCM channels, ADPCM channels, and advanced echo and FIR filtering.

By adding this 10-kilobyte file to your collection, you unlock the full auditory experience of the 1990s arcade era—the crunch of Ryu’s Hadouken, the clatter of Sarah’s machine gun in Alien vs. Predator , and the booming announcer of Marvel vs. Capcom . Happy emulating
In your MAME audio settings, ensure "Stereo" is enabled to actually hear the QSound spatial effects.

MAME is designed to be a "modular" emulator. To keep file sizes manageable and legalities clear, MAME separates the game's code (the ROM) from the hardware's system files (the BIOS or Device ROMs).
In the 1990s, Capcom revolutionized arcade audio by introducing , a proprietary 3D audio processing technology developed by QSound Labs. Integrated heavily into Capcom's CPS2 arcade hardware (powering legendary titles like Street Fighter Alpha , Darkstalkers , and Marvel vs. Capcom ), the QSound subsystem relied on a custom DL-1425 chip.
The file is a vital "device" or supporting ROM required by the Multiple Arcade Machine Emulator (MAME) to run Capcom games that utilize the proprietary QSound audio technology. Since the release of MAME 0.201, this specific file has become a standard requirement for popular titles on Capcom Play System 1 (CPS-1) and CPS-2 hardware, such as Street Fighter II Turbo and Alien vs. Predator . Why You Need qsound_hle.zip
However, around MAME version 0.210 (late 2017), the development team made a significant change. They split the QSound emulation into two distinct files: However, starting around MAME 0
If you attempt to launch a CPS2 arcade game and receive an error stating dl-1425.bin (qsound_hle) NOT FOUND , your emulation setup is missing this device driver.
Without this file, games that rely on the QSound chip will fail to launch, typically returning an error message stating that dl-1425.bin is missing. Relationship Between qsound.zip and qsound_hle.zip
By default, MAME stores its ROMs in:
"HLE" stands for High-Level Emulation . While MAME has a newer, more accurate Low-Level Emulation (LLE) available, most standard setups still rely on the HLE version for performance and compatibility.
