Do not extract the archive. Keep it zipped and place it directly into your main MAME directory: .../MAME/roms/qsound_hle.zip dl-1425
: High-Level Emulation (HLE) simulates the functions of the sound chip without requiring the exact original machine code for every instruction. However, even with HLE, MAME still requires the dl-1425.bin firmware to properly initialize the audio system.
