Metal Slug 6 Mame 0139u1 [verified] Online

: If you are on a PC, using the latest version of MAME (far beyond 0.139u1) provides much better support for later arcade systems.

Originally released in 2006 for the Sammy Atomiswave system, it was the first main entry to move away from Neo Geo hardware. This brought higher-resolution backgrounds and a more "polished" visual look, though some purists miss the grittier pixel art of the originals. New Mechanics: metal slug 6 mame 0139u1
