Let me guess:
If the game knows exactly where the button (or whatever "pressable" thing) is on the screen, then the game just has to rely on the pointer's X and Y coordinates. Simply done using the CPU. That explains why the buttons on the "pause" screen work for you.
As for star bits, pull stars or other non-static 3D objects, the game relies on CPU-to-EFB access (on a color basis? depth basis?) to determine whether the pointer "collides" with those objects. Not as simple as simply executing some code on the CPU -- this is where your GPU is involved in a task.
If your IGP (integrated graphics processor/chipset) doesn't support the texture formats/types required for CPU-to-EFB access emulation to work, then...
