Phil: Do you mean one of the awesomest games in the history of 8-bits? No, I can't recall their street challenge...

I would buy a DS version of Nintendo World Cup too!

These consoles are really common in South America. They are pirate versions of Famicom, commonly called "Family game". You usually have cartridges with "45 in 1", "500 in 1", "999 in 1", etc. which have Super Mario, Galaga, and 5 or 6 more games. The rest are modified versions of the first games. Say, a Contra which starts on level 2 would be "COntra 2", etc. You can also have individual games on cartridges, there´s an adapter to play NES games on it, and viceversa.
Some cartridges even claim to have the latest games, like Pokémon back when they were popular, and recently I even saw one with a Wow image on it.
You can see them on "south american ebays":
