I've bought one today and it is glorious
It comes with 21 games and two controllers. Word of advice for anyone that is going to get one, make sure you have a USB plug since, for some reason, it doesn't come with one.
Here are the games that come with it.
Contra III: The Alien Wars
Donkey Kong Country
Final Fantasy III (In actuality it is FFVI but is was marketed as FFIII in the west at the time)
F-Zero
1991 US
Kirby Super Star

Mega Man
Secret of Mana
Star Fox
Star Fox 2 (never before been released)
Super Ghouls 'n Ghosts
