"It was released for the PlayStation 2 in August 2001, and in the following months it was ported to the GameCube, Game Boy Advance, and Xbox video game systems. Both the GameCube and Xbox ports featured two extra levels that were not present in the PS2 version." -Quote from the Wiki.

So the two levels added in the re-release were Greenville, NC and Venice. Which is why it is in separate categories

The GBA levels are still being researched...
