: While HLE is "lighter" than LLE, 2021-era updates still require a reasonably modern CPU to maintain full-speed audio synchronization.
The 2021 updates to qsoundhle resolved long-standing issues with Capcom arcade audio. Prior to these advancements, users often reported: dl1425bin qsoundhle 2021
For many years, QSound emulation in MAME was imperfect because the internal ROM of the QSound DSP (the chip) had never been dumped. Emulators relied on "HLE" (High-Level Emulation) to simulate the sound, which worked but wasn't 100% accurate to the original hardware. : While HLE is "lighter" than LLE, 2021-era
