romoveing custom sky from wad

[xxbio Warfare11]

Ok, so today i was looking around for a wad that would replace hud weapons, items, and monsters sprites with doom64 sprites. I did find a decent one but my problem is that im trying to use it in psp legacy port and an error comes up becuase of the custom sky textures. Is there any way to edit the wad so that it uses its defult skys?

If the custom skies are simple patch replacements (have the same names as the IWAD sky patches they're replacing) you could simply delete them, though I'd first try renaming to see if that fixes the problem. Otherwise a bit of texture lump editing will be required to restore the default skies. Which wad are you using?
