Finally, I got deeper into modding SH4 and has found that there is a mess with uinits' loadouts still usuall for SH titles. Most units are armed as it is 1945 from the very begning. However there is still ability to change weapones for each ship date by date in the same way as in SH3, thus I've decided to extend my Sink them all mod to SH4. The only thing that annoies me is that in new museum there is no way to view units by year. So, my question is is it possible to get back SH3 museum outlook in SH4?
