Hi everyone. Thanks for being so patient. I haven't forgotten about this mod. I have been working on an SH4 torpedo wake mod, but unfortunately the dev team actually re-hardcoded important parts of the SH4 torpedo.dat file.
I can increase the lengths still, but there are other problems that I can't adjust this time around... such as the total length of wake showing instantly (no wake timer), and the curved edges cannot be smoothed (they are blocky). I have been trying to decode some of the hardcoded stuff, trying to find the correct settings. I will still try to release a version, but sadly it probably won't be as good as my SH3 torp wake mod.
