Weapon duplication:


Select "Item" and press A on an empty slot

during a battle.  Move up until the equipment in that characters

left and right hands appears. Press A on the weapon to

be duplicated. Press B and complete the battle or retreat.

After the battle, equip that character with their weapon in the

same hand it was in. The weapon should have a "2" next

to it. Unequip, then re-equip the weapon. You should now have

one copy of the weapon equipped and another one in inventory.
