Haven't found any bugs yet, but using A on B instead of B on A can sometimes make a difference. For example, it seems that using the cage on the hawk seems to have a slightly different animation from using the hawk on the cage.
uninvite.txt just contains all the text, and all the item names.
uniroom.txt lists the objects contained in each room.
Each room begins with the word "Room" followed by the room number. Then, for every object, the click rectangle is given, then the word "spr" if it is a sprite, followed by the object name, an and optional "when XX" which says that the object is only sometimes shown. Objects are named by what shows on the property screen, or with "Type-XX" where Type is one of the following:
Scenery - Stationary objects. Verbs: Examine, Use, Hit, Speak
FixCont - Stationary objects that contain items. Verbs: Examine, Open, Use, Close

Some objects may accept other commands as well.

Scripts are stored in bank 4 and in bank 7. The master table is at the beginning of bank 4 and is indexed by type: Scenery, FixCont, Trash, Item, Cont, Door, Magic, and more Scenery (shown as Scenery-80 and up in the dump). The sub-tables point to the list of verbs for each object of the given type. The verbs vary depending on the type of object. 6:$ACAB (1acbb in ROM file) lists objects that don't follow the usual pattern, and contains entries like this: type, index, replacement type, and ends with $FF. Type 8 has all the commands: examine, open, use, leave, take, close, hit, speak, move.
