Yeah, great idea. I used the AOB finder wheel way back when OLC made his first versions. My trick allowed you to calculate your intercept angle, which is similar, but not for torpedo's.
It should still work with current AOB finder wheels.

BTW , this thread should be moved to the other SH3 section. It's not a mod so it's in the wrong place here.
