By the looks of it, it must be some sort of Android device placed into an arcade cabinet.
There are 240 games to play, but none of them are well-known titles. Obviously, they didn't want to pay any royalties for using the names. However, all the games are classic ones which I've played couple decades ago.
What I was expecting to see is a HDMI-output, but there is none. All the gaming needs to be done on a tiny screen.
