The Neo Double Games is a cheap ripoff of Nintendo DS. Possibly made around 2004, the Neo Double Games features two card slots, with the top one actually playing the game, with the bottom one being a placeholder, and the games are all 8-bit because of its simplicity. One difference between the NDG and the DS is that NDG has a larger slot for a cart, with the screens having a black border. The black border on the bottom, has a game name, and DS doesn't use cheaply made LCD carts.
There is another version of the NDG, with 2 separate controllers in a edition to the controls on the unit itself.
Games
The games on the system are Soccer, Street Fighter, Submarine Invasion, and Fortress Guardian.
