Given the format chosen is Doom graphics + PNAMES/TEXTURE1, some of the textures should be flats instead.
The DFT22* textures are missing (DFT22BL to DFT22YL).
They were dupes and I removed them after I built the TEXTURE1 lump, fixed.
I guess it's not really important but the DSLVR7*/DSV7* seem to be slightly inconsistent between colors. Scroll through them and you'll see the line that separates the brushed metal from the colored part seem to jump up and down.
They seem fine to me.. maybe it's some illusion thingy again.
Link at OP updated.
