btw the problem to have a XXI in 1939 was solved with Sub Ready 1.1
there's not only basic.cfg and flotilla.cfg to configure: they must be configured with accurancy or you'll find a XXI maybe in '39 but with an horrible ammo too.
In Sub Ready, instead, you can find any u-boot and not only XXI, and finally, you can get inspire for further development.
You can found the "Sub Ready" post in the appropriate section on this forum
It sounds much like a spot for me
i'm sorry.
