How To decompress the Savegame.dat
Move your world to a device that you can transfer the world
Connect the device to the computer
Now create a folder on your desktop named World Backup, and put your world in it
Now create another folder called, well call it whatever you want, then put another copy of your world in it
Now open up Command Prompt
Download the Minecraft Decompressor, I included a hex editor with it
Put your extracted non backup world in 360Revolution and go to contents
Extract the Savegame.dat to the non backup folder
Open Command Prompt
Then drag the minecraft.exe into the Command Prompt. Add a space, then type -d. Then add a space after that Then drag your Savegame.dat into the Command Prompt. Add another space after that. Then drag your Savegame.dat into it again, but this time rename it to decompressed.dat.
It should look like this, but the folder names might be different

C:\Users\Trent>"C:\Users\Trent\Desktop\Minecraft Decompressor\minecraft.exe" -d "C:\Users\Trent\Desktop\Minecraft Decompressor\savegame.dat" "C:\Users\Trent\Desktop\Minecraft Decompressor\decompressed.dat"

Close Close the Command Prompt
Open the decompressed.dat in any hex editor.

Now onto showing what you can do.

List of what you can do
• What the item is
• Count
• Damage
• Slot
• Enchantments

When you load the decompressed.dat file in your editor use Ctrl + F to find foodLevel
It should look like this

Now that you're there you can change the stuff to what you want.
Here is a hex calculator made by [member=begallegal1] to find out what four numbers you want to use for count, the max it can go to is 255.

To change what the item is, you have to change the first four numbers after id into the object you want, which would look like this

Say you want to change it to an End Portal Block, you would change the 01 10 to 00 77. For item IDs, refer to this link, I don't think it's allowed, if it's not, then a moderator can remove it.

Now onto count. For count, it will be the first two numbers after the word Count, it will look like this.

Say you want to change its amount from 64 to 255, You would have to change the 40 to FF.

Now onto damage. It's a bit tricky, but it holds the data for blocks, like the color of wool. Unless it's an item like an axe, then it would be the usage that it has left. I don't know how to show how to edit it, well I know how to for blocks, but I don't have wool on me to show how to do it.

Now onto slot. Slot is where it's located in your inventory. I don't know what happens when you change it to an amount that doesn't exist in the inventory, so I wouldn't mess with it unless you're testing what it does.

For enchantments, refer to these topics.

When you're done, save the file and quit HxD.

Now onto compressing and replacing your Savegame.dat

Open Command Prompt
Pretty much do what you did for decompression, but replace the d with a c, and switch the two file locations.
Here is what it should look like again

C:\Users\Trent>"C:\Users\Trent\Desktop\Minecraft Decompressor\minecraft.exe" -c "C:\Users\Trent\Desktop\Minecraft Decompressor\decompressed.dat" "C:\Users\Trent\Desktop\Minecraft Decompressor\savegame.dat"

Open your world in 360Revolution and go to contents
Replace the original "savegame.dat" with the modded one
Rehash and Resign your world
Open USB Explorer and replace your original world with the modded one
