I agree with you somewhat about the IJN 25mm, although it is a rather large bullet. It was not very accurate, and its rate of fire was not so hot, as well as being cumbersome to load (from what I have read). Ducimus "tuned" those to dissuade a player from surface engagements for the most part. To change it, you need to find the ammunition used in it. According to a randomly picked ship (NKMCS_Heito in FotRSU), the "call" for the weapon is "25mm_Single_base_Jp". A "search" for that in the Library folder turns up a "hit" in "\ShipParts \guns_radar.dat". The triple and double are in there also, as well as the turrets - in FotRSU anyway. TMO is liable to be different in this regard. In the FotRSU example, the "25mm_Single_base_Jp" is "109:node:". I copy its "Id: 0x00adaf8e5dd5c375", and then 'search' on that in the sim file, which gets me "20:wpn_Cannon" parent in the sim file. 21 is the settings node, and under that in the "ammo_storage" section is "AP" and "AA" section that have hex numbers. The "HE" and "SS" are both 0x0, or NULL. You would not be concerned with the AA ammunition, so a 'search' on the "0x3a65f923c98196cc" for the AP (Armour Piercing) in the Shells.dat file. Again though - this is in this FotRSU example - you might find the ammunition in a "Shells_IJN.dat" file, or maybe one of the others. Anyway, when you find your 'hit' for the 'search' in a shells.dat file, open the zon file for it, and find that same hex address in it. Edit the settings node for what you are after...
Now, I went through all of the 'search' stuff because if TMO is anything like FotRSU, which FotRSU is based on TMO, there are a LOT of substitutions for weapons and ammunition, as well as other parts and pieces. You could edit the 25mm ammunition found in the Shells_IJN.zon till you are blue in the face, and all to no avail... finding that address from the gun dat is key, but finding a hit in the shells files is done from within the files. ie: you have to open them up to be able to 'search' in them with the S3D "Ctrl-F" Find function - unless Jeff-Groves comes along and can set you up with an 010 Editor script, or do some "hex magic" for you... The "value" you are looking for is binary, and a text editor search will not find that address for you. I should point out, of course, that you should realize that altering the shell in this situation, does it for ALL guns that use the 20mm shell, including your sub's. Not cool. Another option (in the FotRSU case) is to point the gun at the correct 25mm ammunition, and then tune that ammo to what you want... again though, you want to be certain of what uses that particular ammo before doing something willy-nilly, and willy can be pilly... In this case, it might actually be easier to give the conn a few more points of armor, or maybe afford the crew positions a few more points... so many choices!
