Plus, release dates for Mario Golf (GameCube) and Advance Wars 2 (GBA).Nintendo of America has announced that GameCube sales in February increased 110% over January sales.  The GameCube software tie-ratio now stands at 8.4 games for every system on a year-to-date basis.  The sales boost is attributed to Nintendo's bundle offer, which gives new GameCube owners a free game with the system. 
Game Boy Advance sold more than 250,000 units in February, representing more than 25% of all game hardware sales, despite the fact that an improved version launches later this month.  GameCube and GBA combined to make up 37% of all game hardware sales and more than a quarter of all game sales in February, though Nintendo didn't release a first-party title for either system until mid-March. 
In other news, Pokemon Ruby & Sapphire have sold over 4 million copies in Japan so far, while preorders for The Legend of Zelda: The Wind Waker have reached 600,000 units in North America.
