Historically, arcade emulators used High-Level Emulation (HLE) to simulate the sound of Capcom's QSound chip without actually reading the chip's internal code. However, MAME’s core philosophy is absolute accuracy and historical preservation.

Users frequently run into this issue when upgrading from older emulator setups (such as MAME 0.185 or earlier) to contemporary releases. The issue stems from structural changes in how hardware components are declared in the source code: This commitment to accuracy is why users encounter
