I've a request, if it's not much to ask (that's what I don't know actually, how much work it will take): Is it possible for you, stoffe, to make this program handle all kinds of 2da files? Rather than just binary ones.
The reason I'm asking this is because I'm using your program to install NWN2 modifications, but as you probably know NWN2 uses 2da binary files.
If you can't do it yourself then could I've a look at the source code? That will really help the NWN modding community (not just me, of course).
