After further testing I found out there are a lot of issues with sfx. Random sounds play during the game. Female shouts, male shouts or Shao khan announcements may pop out from anywhere. Game is playable but it need more speed because it's kind of slow now. Plus background music doesn't work.
Plays perfectly. Almost no graphic issues. Only glitch sprites when you uppercut the opponent and it goes flying upwards and breaks the ceiling to enter another stage. Rocks there tend to glitch. Sfx work. Music doesn't work. Very nice.
