I use to do a lot of modding to SH3 and it all worked, torpedo speed, damages, gun reload time... but now I found that these modifications don't work with SH4, it still took a long time to load the deck gun even I already changed the related .sim file with S3D, also the same thing with torpedo speed, the only thing that seems to work is the sub speed outside the library file, is SH4 not using library any more?
