Thanks a lot! It works very well for the textures!
For the menu backgrounds, it seems that they are in .bm format (bkforce.bm, bkmain.bm,...), which isn't supported by Mat16...
I've tried to convert them with bitmat16.9, but it doesn't work, cause it's for Dark Forces BMs.
So, now I'm sure that the menu backgrounds are .bm. How can I convert them?
It must be some kind of "JK menus creation" app, no?
