DFX Skin Generator is a plugin for Winamp which "converts" Winamp skins to DFX skins.
With this program you can make DFX look like a winamp skinned window.
DFX is a DSP plugin for Winamp and this is a seperate application that allows you to generat skins for DFX. The interface is a little colorful and busy, but, it has a fair amount of features to get you on your way to creating a skin for DFX.
You can't use it with packed Winamp skins. The software needs an unzipped version of the Winamp 2 skin.
