It looks great. I'm glad the modding community stuck with SH4 for so long.
Does this version include features from or similar to RSRDC and Improved Ship Physics, and if not - what would be likely to break using them with FOTRSU?
How do the subs "feel" in version 1 compared to TMO or RFB?
e: Some quibbles about S Boats in the Asiatic Fleet, Dec 8, '41
1) I was initially assigned S-23, which was undergoing a refit in California at this time
2) The S Boats in the Asiatic Fleet on 8 DEC 41 start date have 3 inch guns rather than the 4 inch guns they were equipped with
3) Similarly, they are equipped with air detection radar sets on 8 DEC 41 which is not accurate
