Specifically, Ace Attorney Investigations sprites. Layer removing and screenshot combo doesn't work because the text box still shows and blocks anything behind it. Any help is appreciated.
If you want to get them internally from within the ROM, search Google on the graphics formats (NCGR etc.), there should be some software which can map you a complete image into a standard image format, depending on the converted format. Otherwise, someone else may have already done this for this game, so search for those terms.
*Shakes Head* I'm trying to rip sprites for them that they don't already have. They only have people, bgs, and a couple of overlay objects. I know these are here already
