i could have sworn i took the thing out vew versions ago, at least that was planned to happen, i seem to forgot, don't use the batch thingie, it worked few years ago for vicecity and got broken on some unknown time,
it doesn't work, i don't have any plans to make it work. don't use it, instead open each txd separately and use export > export all images as tgas thing.
... And where is that colleditor 2 you are working on for ages?
