Thanks for the detailed feedback
UrPeaceKeeper. Will look into it.
Missile falling back into water is due to engine limitations. As you said, an SDK would probably add more modding options. The maximum 90 degree turn of missiles is intentional. I thought it would look weird during launch to make it flip back towards some target. With the black torpedo I am out of ideas for the moment. Are you using the english version of SH4+U-Boot missions? Are you using other MODs? Did you install with JSGME over a clean SH4? It should definitely be green (ok, textures are a bit in a hurry, because other aspects needed to be solved). The water splash above the tower I know and will be addressed.
