Dl-1425.bin %28qsound — Hle%29 [portable]
If you are trying to find the BIOS, it is usually found within a comprehensive MAME 0.201+ ROM set repository.
Without this file, many Capcom games will load with missing audio or fail to initialize entirely. Because the file is technically copyrighted material owned by the original hardware manufacturers, it is not typically bundled with the emulator software itself. Users are usually required to source the file independently and place it within their emulator's "bios" or "roms" directory—often inside a zip folder named qsound.zip.
To help you get your arcade emulation running smoothly, tell me: Which and version are you currently using? What error message or audio issue are you encountering?
Note: In some cases, creating a copy of qsound.zip and renaming it to qsound_hle.zip ensures compatibility across different arcade games Source. Troubleshooting & Specific Scenarios
In the early 1990s, Capcom partnered with QSound Labs to introduce a revolutionary 3D positional audio technology into arcade cabinets. The hardware manifestation of this partnership was the , which was structurally a customized Western Electric DSP16A digital signal processor containing a mask-programmed, internal read-only memory (ROM).

Without this specific binary file, MAME cannot accurately emulate the audio, leading to the game failing to boot or running without sound. What is qsound_hle?
If you are an avid user of (Multiple Arcade Machine Emulator) or RetroArch , you have likely encountered the frustrating error message: dl-1425.bin (qsound_hle) not found . This error typically pops up when trying to run Capcom Play System 2 (CPS2) games, such as Street Fighter II Turbo , Alien vs. Predator , or Dungeons & Dragons: Tower of Doom .
Which are you using? (RetroArch, standalone MAME, FB Neo, etc.) If you are trying to find the BIOS,
Modern emulators treat arcade machines like modular hardware. A Capcom CPS-2 arcade board is a mother platform, and the game cartridge slots into it. The QSound chip lives on the motherboard, not inside the game cartridge.
If you are building a digitized library of fighting games or side-scrolling beat 'em ups, you cannot escape the need for the QSound BIOS. Capcom utilized this audio chip across its most dominant era.
: Place the qsound.zip archive directly into your emulator's designated roms/ folder alongside your actual game files. Do not unzip it.
If the authentic, exact code has been extracted for modern Low-Level Emulation, why do people still search for the dl-1425.bin (qsound hle) file? Users are usually required to source the file
In emulation ecosystems like MAME (Multiple Arcade Machine Emulator) or FinalBurn Neo, dl-1425.bin acts as the missing piece of bios code. It tells the emulator how the original DSP manipulated audio frequencies and phase shifts to create the QSound effect.
dl-1425.bin is the binary ROM image for the Capcom QSound digital signal processor (DSP). It contains the internal mask-programmed code for the DL-1425 chip , which was widely used in Capcom's CP System II (CPS2) arcade hardware to deliver 3D-surround sound effects. Technical Specifications Hardware Platform: The chip consists of a digital signal processor. Audio Features:
The brains behind this operation was a dedicated chip. On the arcade's printed circuit board (PCB), the QSound processor was a discrete component labeled DL-1425 .
