Though Nintendo of America hasn't issued a formal announcement, the Game Boy Advance titles for Nintendo 3DS Ambassadors are now live on the eShop and available for download. We suspected the international line-up would be true for North America as well, and now the freebie games are available in all territories.
As was the case with the NES Ambassador games, you'll need to download them one at a time by finding them in your download history and tapping "Redownload." On the bright side, the recent firmware update added a "Download Later" option, so you can stack your download queue and then leave the system alone as it grabs all of them for you.
The ten games included are Wario Land 4, Kirby and the Amazing Mirror, Fire Emblem: The Sacred Stones, The Legend of Zelda: Minish Cap, F-Zero: Maximum Velocity, Yoshi's Island: Super Mario Advance 3, Mario Kart: Super Circuit, Metroid Fusion, WarioWare Inc: Mega Microgame$, and Mario vs Donkey Kong. If you were an early adopter, that list should keep you busy for a while.
