Dl1425bin Qsoundhle 2021 [verified] Jun 2026

As MAME moved past version 0.200 and into the early 2020s (including 2021 updates), the structure of CPS-2 ROMs was refined.

Reviewers and users in the emulation community generally highlight the following regarding this specific module:

[Audio Source] ──> [DL-1425 / DSP16A] ──> [Frequency/Timing Alteration] ──> [3D Binaural Image] dl1425bin qsoundhle 2021

The keyword points directly to the state of emulation in and around 2021, when two major events converged:

If you have ever tried to fire up a classic Capcom CP System II (CPS2) game like Street Fighter Alpha 3 , X-Men vs. Street Fighter , or Darkstalkers in a modern version of MAME, you have likely hit a frustrating wall: . This issue centers around the dl-1425.bin file, which contains the internal DSP program ROM for Capcom’s proprietary QSound audio processor . In architectural changes implemented by the MAME development team, this critical audio component was separated into its own virtual audio device package named qsound_hle.zip . As MAME moved past version 0

If you are using platforms like RetroArch with a MAME core, ensure that your system/BIOS directory is properly linked in your RetroArch paths, as this is where the core looks for QSound data.

What are you using (e.g., PC MAME, RetroArch, AtGames Legends device)? This issue centers around the dl-1425

Do not unzip the file. Place the qsound.zip directly into your emulator's "ROMs" directory, alongside the game files (e.g., sf2hf.zip ).

This chip is built around a with a mask-programmed ROM that contains the QSound algorithm. The system can simultaneously handle 16 loopable PCM channels for sound effects and music, and 3 one-shot ADPCM channels, allowing for a far richer and more dynamic audio experience than previous arcade boards.
