The extra bits worked wiht PIXI, but if I set the extra bit for the Giant Football(whick earthquakes and stuns Mario), nothing happens. Instead, it behaves normally. Any way to fix this?
It works just fine for me. What does your list entry look like? How are you placing it in the level?
As a side note, the Giant Football does not stun Mario, it only makes earthquakes with the extra bit set. Neither its description nor its code suggests that it's supposed to stun Mario.
