The standard internal ROM is documented as 4 kilowords, though die photographs show up to 12 kilowords. The correct file for modern emulators typically has a CRC32 of d6cf5ef5 Emulation Role (QSound HLE) In emulation, specifically within MAME (Multiple Arcade Machine Emulator) , there are two ways to handle this chip: LLE (Low-Level Emulation):
The dl-1425.bin file is the digital dump of the firmware or essential sample data required to bootstrap this specific audio environment. dl-1425.bin %28qsound hle%29
If you’ve ever set up , MAME , or certain retro handheld emulation cores (like those in RetroArch or standalone emulators), you might have stumbled upon a missing file error mentioning dl-1425.bin — or seen it inside a BIOS pack labeled "qsound_hle.zip". The standard internal ROM is documented as 4
This tiny binary file is the internal program (the DSP data) for the QSound processor used in Capcom Play System 2 (CPS2) and ZN games. Without it, classic titles like Street Fighter Alpha , Marvel vs. Capcom , and Darkstalkers remain silent or refuse to boot.

This is where the keyword "Qsound HLE" enters the conversation. Emulation generally operates on two fidelity levels: Low-Level Emulation (LLE) and High-Level Emulation (HLE).
