Custom Item Classes
There are 20 item classes labeled as Custom Item Class ##. They have no built-in functionality, but can be given special significance with scripting. The zz### item classes are reserved for future expansion and shouldn't be used.
Items in any of the 20 custom item classes can also be used in trading sequences, with or without scripting. However, custom items used for trading sequences must be set as "Equipment Items" (In other words, items that appear in Link's inventory on the subscreen) and if one wishes to make trading sequences without the use of scripting, the following message string control codes must be used:
- \5\X\X - Goto If Item
- \16\X - Give Item
- \17\X - Take Item
