This patch fixes a bug where if more than 1 hammer bro platform (sprite 9C) and at least one hammer bro (sprite 9B) is loaded into memory, then the platforms will constantly fight over which one has the hammer bro. With this, you can have any combination of these sprites on screen without issue.
This also fixes a minor bug, where the bounce animation of the hammer bro platform only plays the first time you hit it from below.
Pixi 1.2.4 provides a better support for this patch now. Read notes.txt.
Moved Hammer bro's init outside of pixi's custom sprite init hijack
Fixed a bug if you fried hammerbro with a fireball the coin would be stuck to the platform and a hammer bro would still be drawn there.
