The latest in a number of Wii knockoffs. This particular unit has a 16 bit processor, most likely a Genesis-on-a-chip which is becoming increasingly common nowadays. Comes with two Wii-style remotes and various attachments for the sports games. Problem is with these 16-bit Wii knockoffs is the motion contols are extremely crappy. This version comes with two cartridges with the six games on them, there are other versions of this console with the "iSport" label that have the same games built inside.
Currently it's easy to find these things all over the web, selling for far more than they're worth.
