Our friends over at TRMK have recently learned that a new patch has been released for Midway Arcade Treasures: Deluxe Edition! This patch, hot on the heels of the previous patch which fixed the music errors in the MAT2 games, actually fixes two problems present in every single previous version of Mortal Kombat II that was part of Arcade Treasures and Mortal Kombat: Shaolin Monks.
