It's been a while since I did anything with this area, so I'm going off memory here.
Item names are stored in one list. When you go into an equip menu, it loads a pair of values, the start and stop for that equipment type. There are some acceptable values that will be skipped.
For this reason, CT:EC only enables the options that apply to that item's
default equipment type.
