I only have the light version of qED as it was a commercial programm, but there´s a work around for it.
you can manage to extract the wadfile into specs for *.lmp and *.mip textures. But there's glitch, it will show the texture files in 16bit only and that's really bad.
Solution is to export your texture files to *.bmp 256bit and export them to *.pcx.
From there you can import them in adquedit again and export them to *.lmp. Then import them back again and export them to *.mip files.
I know, it's a bit complicated, but it works. One good thing is that adquedit has the quakepal.lmp stored.
So let's say you've got your directory with quakepal.lmp first, then you start adding the others to it and when you use quake101.wad you'll be able to import them in Wally
and compose your own wad file for research.
I know it is quiet a lot of hussle, but as I suspect you're a tester it shouldn'ty be that much work.
