"Old version", specifically;

One problem I found with it, it says for 1.4 and 1.5, but to use it in 1.4 without crashing you have to do a folder by folder comparison of the \Data\Sea\ subfolders and delete the ships that are in 1.5 but not 1.4. Example NCA_Deutschland is in the mod but not in SH4 version 1.4, so the .sim file throws a hissy fit over non existent files. If you have version 1.5 you don't have to worry about it, but the mod is NOT compatible as advertised with 1.4 out of the box, it requires some tweaking.
