In the world of MAME, every piece of original arcade hardware needs to be emulated in software. For CPS2 games, this includes emulating the DL-1425 QSound chip. The primary way to do this is by using a copy of the original chip's ROM data, which is contained in a file named dl-1425.bin . Without this specific file, MAME cannot correctly emulate the audio hardware, and the game will refuse to run.
This method only works if your existing qsound.zip already contains a correctly named dl-1425.bin file. Many older ROM sets contain qsound.bin instead. However, for a significant number of users, this simple rename trick is all that's needed.
Ensure multiple paths are separated properly with semicolons. This prevents the engine from skipping over system device structures during its directory audit. mame dl1425bin top
Once you've placed qsound_hle.zip in your ROMs folder, verify the installation:
For years, early arcade emulators used High-Level Emulation (HLE) to approximate this sound processing without running the actual chip code. However, emulation developers eventually decapped the physical chip, read its physical silicon layers, and dumped the exact execution data into a .
Here are the most common solutions to get your top games running, ranked from simplest to most permanent. 1. Update Your QSound BIOS File This public link is valid for 7 days
Understanding why this error happens—and how to fix it—requires a deep dive into how MAME handles sub-device firmware, changes in emulation accuracy, and modern romset management. 🕹️ What is dl-1425.bin and QSound?
Users frequently report that simply renaming a correct copy of "qsound.zip" to "qsound_hle.zip" (ensuring it contains "dl-1425.bin") fixes boot issues in LaunchBox and other front-ends.
Historically, this file is associated with specific arcade platforms, most notably those developed by companies like Sammy or used in various "Prize" or "Medal" games popular in Japanese arcades. Because MAME aims for "pixel-perfect" accuracy, it does not simulate these BIOS functions through high-level emulation; it requires the original, bit-for-bit dump of the chip. This commitment to accuracy is why users encounter errors when the file is missing; MAME refuses to guess how the hardware should behave, insisting instead on the original data.

The file represents the BIOS or ROM data for the Dallas DS1425 , a "Button Top" multi-chip module used in various arcade systems and early computer hardware supported by the MAME (Multiple Arcade Machine Emulator) project . While seemingly just a small piece of binary code, it highlights the technical intersection of hardware security, data preservation, and the philosophy of emulation. The Role of the DS1425
The file is a critical component of the QSound audio system used in many Capcom arcade games (such as Street Fighter Alpha 2 and Alien vs. Predator ) within the MAME emulator. If you are encountering a "dl-1425.bin not found" error, it is typically because your emulator requires a specific BIOS file to process audio for these titles. Troubleshooting the dl-1425.bin Error
