Item Editor

The item editor is an advanced editing feature. Understanding how the ROM stores items internally may make using this editor easier. In the ROM item data is stored per-level. For each level there are a list of "item data entries." Each of these define all of the items on a row of the map (there can not be more than one per row). Each item data entry contains one or more "room entries," which define all of the items in a room (there is usually only one item in a room).

To move items around, click on an item in the map and drag it around with the mouse. Note that when you move an item up and down, all other items in the same item data entry move vertically with it. Also note that you can not drag items past each other in the same item data entry. In the current version, this limitation is imposed for technical reasons.

To edit items in a screen, click an item on the map. The screen you clicked will be displayed on the bottom. Two lists will appear on the right. The top list contains numbered items (although there is only one item in most rooms) and the bottom list presents options for that item. There are different kinds of items: elevators, palette swaps, power-ups, and even doors and enemies. In the current version of Editroid, you can not change item data from one type to another.

There is also a checkbox labeled "Easy Mode." When this is checked, the ROM's password data is updated to reflect changes made to item data. This allows you to move and change power-ups and still have the password system work properly. If you prefer to manage password data yourself through the Password Data Editor, uncheck this box.
