How do I mod weapon/body stats

[3drts]

What program can I use to mod in game stats?
Specifically I would like to increase the base damage done by the Assault cannon (to that of the medium cannon or more, as they are both supposed to be 76mm cannons)

Increase the VToL ammo capacity for the Railgun, Needlegun, Flashlight laser, and all the machineguns.

Increase engine output of a body... etc

Also, how much work does it take to add a new weapon- I'd like to add an improved Mini-rocket pod- Just as the lancer leads to the scourge missile I want to see Mini-pod rockets lead to something like "Hydra rockets" (like the 76mm FFARs on an apache, or the MK 66 76mm rocket pod our fixed wing aircraft can use)- something that would be of use at least against 2nd campaign technology.

Maybe you can try this:

index.php?topic=889.0

note that this only works with svn data,just go grab Giel nightly build in his 'nightly build' thread if you are on windows.
