dumb editing question :/

is it posable to change dooms colormap and playpal in zdoom. so i can use better than 8bit textures?

It's possible to change the COLORMAP and the PLAYPAL entries. However, that won't give you better than "8-bit textures". It will give you the ability to customize the 256 colors. The doom engines will still use 256 color (or 8-bit) textures.
