It dont worked
Let me explain: I successfully imported the model on max, I corrected the cables without problems.
The problem is when I export the model:
1) The exported obj is not the same size of the original one, is between 50-100 bites little.
2) Sansal tool ask for a mtl file of the same name of the modificied model (I discover it by checking the status bar on the tool) so I use the mtl on the dat file and create a new one based on it with the same name of the modificied file.
Well, when I load it into the game and check the type VIIC, the game close and drop to windows.
Well, altough I cannot fix the problem until a correct obj export input to max works, the procedures to fix the problem are the following:
1) Go to data/Objects and look for the turm .dat you want to correct, fix the problem is not as easy to modific one file, you will have to check what turms are the problem, because the default models available at data/Submarines dont have any problem (but you can load them to help you correct the turms).
2) Select them with Sansal tool and extract, I recomend you make a folder somewhere and extract it there because there are no subfolders for the turms and you will get a very big 3D folder, dont forget to backup.
3) Look on the 3D folder for somewhat Turm7c_1_High.obj or something like that, there are a shadow (with SHD on front) and a reflect model, you can fix the problems there if you want.
4) Once on the 3D program you load the turm and the sub as reference. On my case I had to rise and move foward the turret to place it on the correct position, on the type VIIC was easy, just make the backend attach points overlap each other. Then you have to move the vertex to a)make them in the correct position b) correct the "balls" that for sure will be floating on the space after the cable move c) make the cable to have a "natural" patern.
5) Then find something that can export it and compatible with the sim.
On point 4 I was able to do it, it went really nice, however it didnt worked. Maybe other modeler can have the correct tool to do that.
