This BG is used in the SNES version of Earthworm Jim, where you battle Psycrow. Uses about 4 GFX pages, but you can also use a FG and consumes over a Map16 page and a half. It also uses 3 palettes, but you should have room for colors.
A really good (and really big rip), however you dont have to include a readme.txt or anything of the sorts unless there are special instructions to the graphics usage or anything. Everything you have explained in the .txt is also explained in the submission description. I have went ahead and removed it from this submission but please keep that in mind for future submissions.
