Easiest way to dump and replace textures for DX9 games?

[kmldkmdmweid]

As the title says, I'm trying to find the easiest solution to dump and replace textures in a DirectX9 game, in this case, Forgotten Realms: Demon Stone. To my knowledge, there are no programs that can pack and unpack the game's textures (which are in .xbi format) so I have tried experimenting with other tools.

I have tried Texmod, which does work, but unfortunately takes a lot of manual input to dump all the loaded textures in memory. I've also tried Special K but it seems it doesn't really work with this game in particular. Anyone knows of any other tool, or how to automate texture dumping with Texmod?
