Excluding Weapons from Use With Genji Glove

I've mostly created the logic for the second piece, which examines the item in the list to see if it can ALSO support a second weapon, but I don't know how to evaluate the LIST item's properties rather than the equipped items.

I don't know if I understand this correctly, but if your item is in the list (you need to loop the list) multiply item ID by $1E (size of item data), store in X and load your property byte with a LDA $D850??,X (see item properties).
