O.K. all you AoE/RoR fans here are a couple of mod packs that allow you 
to use snow in your scenarios.

Specific install/removal instructions can be found in each zip file 
for the different games.

What these mod packs do is replace some of the slp files in the 
graphics.drs file.
The graphics that are changed are the gaia "grass clumps" and some of
the pine trees.

These have been tested and I have not had any problems with them.
If you encounter any problems after using these mod packs please e-mail
me at jmwjmw@earthlink.net and I will try and see if I can help. 

Special Thanks to Stoyen Ratchev for his DRSbuild utility and 
Joseph Knight for his SLP studio ver 1.7. Great utilities guys !
Without thier great work on these utilities I would not have been able
bring these mod packs to you.

I hope you all enjoy what I've done and are able to make use of them.
