1.) An explaination of the patches:
*****************************************


This directory contains patches grouped by various categories, as seen above. The layout was 
designed to present all currently known sprite patches in an easy to browze and understand 
format.

The laout is as follows; under each major section will be a list of subsections, say, each 
individual sprite, or a certain part of the patches. Some patches, such as sprite movement 
patches will be by sprite and simply list the patch, while others will be in an 'options list' 

Options lists are lists of each sprites patch, with the value that sprite uses, an example is 
the sprite-keen interaction section. Here a list of patches for all the sprites is shown, 
with each patch saying what sprite it is for, and what the value used does. This is a concise 
way of compressing a lot of patches. In this case, if we want to make the Vort use the Tantalus 
property, we simply use the Vort patch but put the *Tantalus'* value in it.

All patches here, unless otherwise stated use *the values normally found in the game*

This is a list of all the sprites in the game and for whom patches will be found here; it is 
surprising how many sprites there are [Twenty!]
