OK what are MOD's, i see alot of people talking about them and i kinda got that their visual upgrades to the game for extra scenery or somthing holidays whatnot, but once you put one in, doesnt it erase your original files and how do you take them out, i have seen a couple from the last game *vv1* in screen shots and on the examples, but i dont want to permanetly erase the original theme. just a good explaination on how to do it would be wonderfull thanks

A "mod" is essentially just a modification. If you saw the topic I made, (Future: VV2 mods?) you'll notice I wanted a mod that changed the colors of the mushrooms, as brown mushrooms are really hard for me to see. Someone who knew how to do it, made one for me, so now I have bright purple mushrooms in my game. I made a backup copy of the original file that I was wanting to "mod" (modify). It's safe in another place, so if I want to put everything back the way it was, I can just take my backup copy, and overwrite the "modded" file with it.

thanks, im just worried that the game would never be the same, i understand modifying the images, i have made a few changes myself, like making the mushrooms brighter so i could spot them faster, and i decorated my hand with a cuff and ring. In the first vv i changed the color of the boulder and the berries, i hate yellow so they are now red and blue berries lol but i never backed up those files cause they were permanent changes, i will just have to make a whole other file for the backups thanks

Do you just edit the .png files (the sprites) to do that?

Where are these Mods? Is it like a "patch" somewhere that we can load into our game?

There are no mods for VV:TLC yet. There are a few mods for VV:ANH for Christmas, Thanksgiving and Halloween. They are located in the guide section here.
