It's not an authentic one, but the Arcade1Up Mortal Kombat II Deluxe version. Still an amazing experience. It's tall without any booster needed, very tactile and responsive controls and has all the classic 2D MK's including MK3 and Ultimate versions. The speakers are beastly and monitor quality amazing. In the video below what you're hearing is at the lowest setting of volume. I dont think my phone picked it up too well though. There's also an option to add retro scan lines to the games which is not enabled in this footage. You can also play online with other players across the world. Looks like there was an invite halfway through the video. The machine takes a few hours to construct but definitely worth it for that arcade experience.
