The VG Resource

I'm using zhangjiequan's AssetStudio: https://github.com/zhangjiequan/AssetStudio
and for some android games that function on Unity, the Texture 2D sprites are unreadable. How can this be fixed?

I don't know, maybe is a misconnection between the AssetStudio and the Asset, but I am sure some of these assets are encoded and i don't know how to decode them either.
