Yesterday I bought the game on Steam after seeing some YouTube videos, and was immediately annoyed at how twitchy the camera rotation was, so I did some digging and found a hard-coded floating point constant that can be used to tweak sensitivity. It's located at offset 0x11daa4 in sh3.exe (seems valid for both raw Steam and h.sie patched one), and by default is set to 1/600. Thus for instance changing bytes like this to reduce it to 1/3600 makes all camera rotations with the mouse a lot slower:
Code:
0011DAA4: 0e -> b4
0011DAA5: 74 -> a2
0011DAA6: DA -> 91
0011DAA7: 3a -> 39
Maybe someone can make a more convenient way to do this, but it works for me
