I did find out some cq_itemtype fields in the itemtype.dat base on translating from hex value to decimal and then comparing them to cq_itemtype field's values manually.
Also tried to add a new item to the end of itemtype.dat which has same field's values as an existed item (only changing the item's ID of course). It ended up not showing up in the character's cabin even if I added the image .dds in MapItem and ItemIcon. Checking the Database showed that the new item was there in the cabin, but no image and the cell still got taken
Is there a way to editing this file correctly or am I missing something
Much appriciate for your help guys !
