memory hooking a game

[Ibrahim90]

title says it all..

I've been making a mod for Rome; total war, based on the Seven years war. Generally, the engine does well, and I'm able to work with the engine with ease. However,  Canister is proving more problematic: currently, the game does not (as far as anyone knows) have the ability to creating a shotgun spreading projectile (e.g. canister/grapeshot).

However, Medieval II: total kingdoms does have a means of doing that, via an xml file. This xml file could in theory work with Rome total war (same programming language), but I need a way to tell the engine to read the file. Which as far as I can tell needs a memory hook in the run-time process--ideally using a dll or something. This would not only allow for the game to implement canister, but perhaps improve the already present artillery.

which is why I write here: anyone here can do this, or alternately show me the means? figured someone here can program. both should be using C++ or similar.
