From what I know, a lot of the data on a disc is junk data, or filler data. So I guess they could remove a lot of that data and replace it with the other game.
Gamecube games are like a third of the size of wii games, and these 2 games weren't really anything that couldn't be done on the gamecube visually, so perhaps even together, these didn't take up the whole wii disc.
