Neat! Will it extract the KFTIMs from the larger files or does it work on the already extracted KFTIMs?
As far as SoM TXR files, it's been a long time since I dealt with them and I don't have much time to refresh my memory right now. Off the top of my head, there are 3 different sub types which are all similar to a BMP but with a changed header, and they are not flipped upside down like BMPs are in their data.
Like a BMP, they come in palleted 256 or less color variety, a non-palleted "true color", and lastly, low color TXR files for map Pieces have some funky data tacked onto their end that is presumably used for shadows. That data can be discarded when converting to a BMP. 
EDIT: Hee hee I get a crash when I go to import KFTIM and then cancel. My stuff always does that because I forget to tell the program what to do if the "select" box returns empty. I'm glad someone else does the same mistake. Now I don't feel so stupit
