normal map shader cf.normals.jxs

Hi guys

I was wondering if there was a newer updated version somewhere in here of a normal map shader

All found was this one from back in 2003 cf.normals.jxs.
The quality is not insane
The 2 params don't seem to work as well .
I did download and try vade 001. shader but no luck getting it to work as well.

I am wishing something like this but from within jitter
