Gambit37,
You have post some Eob and DHack wallsets. But the color Palette is wrong.
If you manage to extract the pictures in 256 color palette in pcx format if its possible, I can correct the palette. (But also the original extract not in 16Bit colors and reduce to 8bit colors after , because the color mapper will destoyed).
You must extract from the source image as 256 colors even is the palette wrong.
Did you use XWE to extract the images from DHack?
If you used XWE for extraction what version you have used or what software you have use to extract , to try to extract mysolf and correct the color palette.
For example , cave colors , mines , and all backdrops have fault colors , all backdrops are almost red.
Thank you....
