Well shoot - it turns out several of the save-game-related files are in fact just text files readable via notepad, but none of those that I could find appear to be where the data on torp and fuel status are kept - I guess that's probably in the ___.sav file, which seems to be some special, non-text format file that I can't seem to peer into
I figured it was too easy for that to work. Anybody who knows what they're doing have any ideas on where this data is stored and how one might tweak it from outside the game?
