Released in 2006 on the Sammy Atomiswave hardware—rather than the traditional Neo-Geo MVS—this title pushed the franchise forward with new characters, branching paths, and intense gameplay mechanics.
If your hardware allows it, the Flycast or Reicast cores (Dreamcast/Atomiswave emulators) typically provide much smoother performance for this specific title than legacy MAME builds. Verdict metal slug 6 mame 0139u1
