Dl-1425.bin — %28qsound Hle%29 ((better))

The file dl-1425.bin is a critical audio firmware component required for High-Level Emulation (HLE) of the QSound system, primarily used in Capcom's CPS2 (Capcom Play System 2) arcade hardware. Understanding dl-1425.bin and QSound HLE

dl-1425.bin is the internal ROM data for the Capcom QSound processor, a digital signal processor (DSP) based on the dl-1425.bin %28qsound hle%29

You do not need to emulate the ADSP-2105 (the QSound DSP chip) at all.
You only need to simulate:
- Benefit: Significantly lower CPU usage.
- Benefit: Easier portability to low-power devices (mobile phones, Raspberry Pi).
- Drawback: Historically, early HLE implementations suffered from "scratchy" audio or incorrect echo depth compared to the real hardware.
The High-Level Emulation (HLE) Shift: Newer versions of MAME (starting around 0.201) moved toward more accurate High-Level Emulation. The file dl-1425
