|     HOW IT WORKS:     |
-------------------------

* First you open the Mario 64 rom.

* Then you click the Edit Object button and select from many different objects in the game, These objects are basically like for instance Pink Bom-Omb 1, is one of the two friendly Bom-Ombs you see at the start of Level 1 (Bob-Omb's Battlefield), and they tell you a bit about the level.

* Next you can edit the X,Y,Z position. Now in a hex editor you would have to edit two seperate 1 byte hex values to get the X,Y or Z position but I used a little trick so it merges them together for you, so when editing object positions, just change "X,Y,Z Position :" not the 1/2 or 2/2 version.

The same goes for rotation.

*Object Id is basically what the object looks like, so you could make the King Bom-Omb boss look like a Star and etc.

*Mission Id is what Missions the character appears on, for example Koopa the Quick is only found on Mission 2 hence why the value for the mission is "02"
But the Rolling Balls are on every mission so their value is "1F".

*Ram Segment Code is how the Object behaves, so if you want to make two of the same object in the map, copy the Object Id and Segment Code to another object, move it's position and voila, two of the same object. An object you could use could be a Chain Chomp, Imagine two next to each other!

*Parameter Code - This also has something to do with how the object behaves.
