or "scratchy" sound effects depending on the device's CPU power. The Verdict Cause: The audio emulation for Atomiswave's SPU (Sound

• Cause: The audio emulation for Atomiswave's SPU (Sound Processor) in 0.139u1 is not perfect.
• Fix: In mame.ini, set sound to 0 (mute) to check if gameplay improves. If you need sound, set audio_latency to 4.

Modern MAME (0.250+) runs Metal Slug 6 flawlessly at full speed with perfect sound. However, 0.139u1 holds nostalgic value for emulation historians. It represents the exact moment when a "unplayable" arcade classic crossed the threshold into "weekend playable." Many emulation guides from 2011–2013 specifically cite 0.139u1 as the first truly usable build for Atomiswave games.
