Well, I'm playing around with the Goblin Editor and started merging and building the submarine from the various rooms. Of course.. I don't know what I'm doing but I'm walking around the sub and looking at things from angles and locations not allowed in the SH5 interface. Seeing lots of detail.
I wish I could click on an object (say Enigma Machine) and then be able to find the file/object that is.. so I can replace it.. or add things in various locations.. whatever. Maybe it's just a pipe dream.
