If you are playing a RPG with a save/load system you will want to edit your items too if you want to make a good charecter
You Type in the items name
Like for an example Twilight's RPG
You want the item Battle Guantlets.You Open the items.txt then you press ctrl+f and the search is going to pop up
you type in Battle Guantlets and its going to send you to the spot marked with red in the spoiler
You scroll a little up until you find the green part.That is the Items Raw Code.
If the map Is cheated with JJ's cp you type -spawn I035 and the item is going to spawn.
