The commands.cfg and adding MnID lines really didn't do the trick, so I looked how the dial for selecting one tube or salvo worked and then kind of copied some of that and messing with the figures and textures.
So now I have a dial showing up in the right place, and it IS sort of working, except that the dial is showing M all the time, and I should maybe reverse M and A, because the game starts on auto. So one cannot really click it so the dial moves. One has to click and drag on the dial sideways, and then you can change between Manual and Auto.
So in the commands.cfg, I have this:
[Cmd131]
Name=Toggle_TDC_autoupdate
Ctxt=1
;MnID=0x2620D001
;MnID=0x2820D001
Key0=0x41,Rs,"Right Shift + A"
This way, you can always use the keyboard.
For dials.cfg, I had to come up with a new Type, since there was no Type for the attack map autoupdate button, and it seems Type37 works, so...
[Dial90]
Name=Autoupdate; Carotio`s Torpedo Dials, Auto-Manuel Peri
Type=37; Toggle_TDC_autoupdate
Cmd=Toggle_TDC_autoupdate
Dial=0x2620D002
CrtVal=0x2620D001
NewVal=0x0
DialVal=-45,45
RealVal=0,1; 0-auto or 1-manuel
Circular=Yes
CmdOnDrag=Yes
SndStep=1
SndList=2,Menu.TDC.TorpedoSalvo_T,0.1,Menu.TDC.Tor pedoSalvo_S,1,
[Dial91]
Name=Autoupdate; Carotio`s Torpedo Dials, Auto-Manuel UZO
Type=37; Toggle_TDC_autoupdate
Cmd=Toggle_TDC_autoupdate
Dial=0x2820D002
CrtVal=0x2820D001
NewVal=0x0
DialVal=-45,45
RealVal=0,1; 0-auto or 1-manuel
Circular=Yes
CmdOnDrag=Yes
SndStep=1
SndList=2,Menu.TDC.TorpedoSalvo_T,0.1,Menu.TDC.Tor pedoSalvo_S,1,
I'm too tired to experiment anymore this night, so any suggestions to how to make the dial switch from side to side by editing these lines in my dials.cfg?
On screen, it looks like this for now:
