It might not be appropriate to post this message here, maybe it should go in the "other variants", but if the guy who made these relief tiles is reading this message, or if you have his email, could you send a pm.
The TripleA developers wants to use them in the TripleA package, and they need a permission.
I uploaded the relieftiles here: http://www.mediafire.com/download.php?1fj2zm5iwnx
It was downscaled/converted from ILs AA50 map.
AA50 in TripleA looks much better with these relief tiles than the simple TripleA map.
