If the CRC matches, the error will disappear.

If an older build specifically demands qsound.zip , copy your functional qsound_hle.zip file. Rename that copied file to .

Capcom’s CPS-1 hardware (released 1988-1995) used a modular design: a main PCB (printed circuit board) with sub-boards for sound and graphics. The dl-1425.bin file is almost always associated with the of CPS-1 games. If the CRC matches, the error will disappear

Interestingly, dl-1425.bin also contains the game's title screen compression routine and the code for the character selection screen.

Historically, older versions of MAME used an alternative file named qsound.bin alongside crude High-Level Emulation (HLE) to approximate arcade audio. However, as the MAME Development Team shifted focus toward perfect historical preservation, audio engineers successfully decapped the physical DL-1425 silicon chip to extract its true internal code. This accurate code is what makes up dl-1425.bin .

In modern versions of MAME (v0.186 and later), dl-1425.bin replaced the older, less accurate qsound.bin . This change was made following a successful "decap" (mechanical opening) and dump of the original Capcom chip, allowing for much higher emulation accuracy of the QSound audio hardware. : Internal ROM for the QSound DSP.

Before dissecting the file itself, we must understand the ecosystem. MAME (Multiple Arcade Machine Emulator) is a decades-spanning project that aims to preserve gaming history. Unlike a standard console emulator (like one for the SNES or Genesis), MAME emulates the hardware of arcade cabinets—each of which was a custom-built computer.
