As you know the most active threads at subsim forum are SH3/4/5 mods.
Modding is the core, critical and the strongest featore of Silent Hunter series.
For example: the first mode for SH5 (Kriegsmarine historical accuracy ensign) was published after 2 days after SH5 release date (notice that Nazi Haken-kreuz is banned in EU, similar to Kyokujitsu-ki Japanese navy military ensign in Korea).
I've just downloaded "build 144" of HMS Marulken to see directories structure and I have to say that all in-game units / weapon data / navy ensigns / textures / missions are highly-coded and hided deeply at game files.
Hard to say it but
HMS Markulen is not friendly moddable at this stage and is not possible to dominate Silent Hunter series. Cooperation and multicrew option is not key to seccess here.
