Battle Background Offsets

As of right now, we can't really hack a battle background because you can't place any tiles you create, only modify them.

Excuse my noobness, but what does Zeemis mean by only modify them? You can modify the drawing but not the color? Because, im currently ripping some animation im missing for my project, and since a lot of the animation have transparency, the background are screwing the animation. So, i was wondering if it was doable to put the background completely white?

Each battle background is comprised of several tiles that repeat. They repeat to save space on the rom, this ultimately means that those backgrounds you see aren't actually whole but instead a set of tiles cleverly placed to put together a picture. Think of using several copies of a same piece of a jigsaw puzzle to put it together.
I've hacked a battle background before, it is possible, but only to an extent.
Read this thread I created awhile ago on how to.
