It's no commercial loss to anyone downloading the DOS game 'Das Boot' anymore because it's so old. But still it's a commercial program which it's developers did not give out for free download, so it just falls under the category of abandonware.
This is not the case with SH3Gen, because this is not commercial at all.
If I got the point here
.
And if THAT is not forbidden: a little hint on using goolge:
dos games "das boot"
will give you plenty of results on this game
