Note

This build introduces objects that live freely on a short object pool. These objects can have a free position on the world and may also hold X and Y speed information. So now we can have very interesting objects such as moving rings and shields, but also other kinds of objects as well!

This build had two revisions. The second one introduces a fix for the MDEC which goes lighter on the disc reader, so now FMVs will likely play without much hazzle.
