QSound was a specialized 3D audio technology licensed by Capcom in the 1990s. Because MAME developers do not own the rights to the internal QSound code, they cannot package these ROM files with the emulator software itself, requiring users to source them separately to avoid copyright issues.

The core component required to resolve Capcom sound issues in modern arcade emulation is , a critical auxiliary device ROM used by the Multiple Arcade Machine Emulator (MAME) . This file contains the essential data for High-Level Emulation (HLE) of Capcom’s proprietary QSound audio hardware .
