What I've done so far:

- Identified variable which contains the CO2 level.
- Found assembler routine which modifies/cumulates that variable.
- Found a way how to determine Hex-address of Silent - Running - Status Flag. (As most of the variables, it changes it's address, every time one starts the game)

So I am lightly optimistic that some CO2 manipulation can be done.
Next milestones for the next days:

- Find out how to determine number of currently living crew members. dead men don't breathe. (maybe difficult?)
- Determine U-Boat Type
- Modify the assembler routine accordingly.

Even if I am unable to find the number of living crew members, it seems possible to enlarge diving times and consider the Silent-Running. That would be an progress.

Or alternatively I could take the number of crew at mission start.
