I completely re-worked the torpedo and deck gun cheats from the v1.2 patch.
Cheat files:
SH4 Deck Gun Cheats
SH4 Torpedo Cheats
Divx movies of the cheats:
3000m blast-radius deckgun movie
100m blast-radius torpedo movie
They aren't compatible with JGSME because I'd have to break apart the different versions. However, you just copy 'n paste the files into the folder -- I've included the original v1.2 files to make things easy to restore.
***********************************************
1. The deckgun cheat is self-explainatory. It only applies to the AP/HE shells on the 4/50" deck gun -- both shell types are identical. The folder name indicates the blast radius of the shells. 100m blast radius will take out single boats, the kilometer blasts will take out convoys. Make sure you're out of the blast radius.
**************************************************
2. The torpedo cheats are a little different because there are two types, and the second type is dependent on the first. There would be no point in breaking them apart because the second mod will be utterly useless with stock torpedoes.
2a. The first set of 3 folders indicates the blast radius of the warhead. 100m will destroy single boats, the 1/2/3km blasts can destroy multiple. Copy one of these files into the sh4/data/library folder, as indicated. All torpedo types have been altered in these cheats, so they are all packing the same warhead strength.
2b. The second set of 3 folders combine varying magnetic detonator sensitivities (20m, 200m, 500m) and altered arming runs (150m, 1100m, 3100m), as well as increased running range (10,000 meters on both slow and fast setting) --
but only on the Mark-14 torpedo. This second "magdet" cheat only applies to the Mark 14 torpedo.
If you are using the 1/2/3km blast radius, is is
*HIGHLY* advised that you also use the 1100m or 3100m arming run cheats -- a premature detonation will end your game. Remember that this second torpedo cheat will only work if combined with an appropriate one from the first set (don't combine the 100m blast radius with the 500m magdet), and that it only applies to the Mark-14. So a Mark-27 at 12kts with a 3000km warhead can end your career with a premature detonation.
*********************************************
As shown in the video, the torpedo detonates when it closes to within 200m of the target. Could have missed astern or forward and it would have gone off the same.
Here's a picture to show what is possible with the large blast-radius cheats. I forget the tonnage involved, but there were two +30kt ships in there -- probably topped 150,000 tons for the whole load.
