I know you only make matching themes for nuke 6.5 and phpBB 2.1.
I don't want to upgrade my site to 6.5.
I convert original phpBB theme to phpbbport 2.0.6 and nuke 6.0
On my local machine everything is ok but not tested 100%

You can download it by clicking this link http://breakolami.free.fr/fiblue3d.zip

Now you can make a matching theme pack for 6.5 and 6.0 and make it downlodable in your gallery.
