Brand new retro game system based on the original Nintendo NES, with 2 controllers. This system is preloaded with hundreds of classic Nintendo NES games including Super Mario Bros, Contra, Donkey Kong, Dr. Mario, Paperboy, Tetris 2, Teenage Mutant Ninja Turtles, Excitebike, Pac Man, Dig Dug, Galaga, Street Fighter, Mortal Combat 4, Spy Hunter, Double Dragon, Q-bert, 1942, Spiderman, Batman, Bomberman, Sudoku, Pikachu, and much more. *Plus* it has two super rare Japanese Mario games. One in which he carries a karate stick and another in which he does Kung Fu. There are also multiple versions of some games, for example there are multiple Contras, Double Dragons, Tiny Toon Adventures, Donkey Kongs, Teenage Mutant Ninja Turtles, and so. So if your game had sequels, they may be included, check the list or PM me. However this system is not an exhaustive list of all NES games. Some are missing. It doesn't have Zelda, Kirby, or a handful of sports games. The box says 620 games, however in the menu some are repeats. It probably has about 400+ different games. I don't know, I didn't count them. This is based on the original Nintendo NES and has NES games, but this is *NOT* a Nintendo product. It is an aftermarket game console. But the price is good for the product. Contra alone still sells for $30. This system is preloaded with games and does not take cartridges. The unit itself is a mini console and smaller than the original NES. The controllers are the same size with the same button configuration. It does use an AV cable to hook up to your TV (the red/yellow/white) plug. Most TVs have that hook up, but some smart TVs don't. Check your TV before buying. If you only have an HDMI you will need an adapter. They are cheap online.
