Hi j
It's not that complicated once you start to understand what you need to do.
You can still do a fast 90 degree shoot by using your own course and the targets.
The Option File Edtor Viewer can be set up to give you the true bearing and the targets course, all you need to do is find the speed.
You do not need to use the stadimeter or identify the target.
Position 800 to 1000 metres from the target.
Set your periscope cross hair at 0 is AOB 90 degrees.
The targets speed and torpedo speed will give you the lead angle for the periscope bearing firing position with the 2 dial arrows pointing verically.
Enter the speed, AOB, range 1000 metres in the TDC manually.
The 4 bearing method and RAOBF wheel are not essential for real navigation they are just options that are there for those who wish to use them.
This is just a brief outline of what can be done and you can play real navigation without 100% difficulty until you are ready.
