It's hard to know exactly what part of their profit Nintendo made off the GameCube to be honest, they had the GBA selling like gangbusters through 2004 and then had GBA + DS picking up the slack for 2005, and then the DS exploded towards the end of 2005 in Japan.
Also in the early part of the 2000s they were making a ton of money from Pokemon merchandising too as it everywhere.
