The
ROM file is packed with data (images, levels, etc) and there's simply no more free space.
You could start by clearing all levels; making all rooms empty.
A quick way to clear a single room is by clicking the
middle mouse button on one of the room's tiles.
In theory the program could be modified to allow its users to add more objects.
However, if you first clear out all rooms and don't create huge levels, you won't run into issues.
It would be too much unpleasant work for me to modify the program to allow more objects.
