i would like to install this on just one texture pack how would i do that?
You know, in the minecraft.jar the sprites for IC2 are located in "ic2/sprites/xxx.png"
If you open your texture pack, create a new folder called "ic2", go inside that folder and create another folder called "sprites".
In the "sprites" folder, you can throw all the texture files, such as "block_0.png"/"item_0.png".
Now when you open Minecraft, the texture pack will load, which includes your sprites.
