This occurs because modern MAME versions (0.140 and later) the QSound microcode to emulate audio accurately. Without it, the emulator cannot drive the virtual QSound DSP, and it halts execution out of preservation integrity.

As of 2025, MAME’s LLE QSound is considered definitive. The microcode dumps inside qsound-hle.zip are verified and complete. However, researchers continue to refine the emulation of the DSP’s analog path (filters, amplifiers, and noise shaping). Future MAME versions may require updated QSound data files, but the core qsound-hle.zip will likely remain compatible for years. What is qsound_hle
You generally do extract this zip file. Emulators like MAME and FinalBurn require the ROMs to remain zipped.
