I have a boot ROM here that I'd like to modify the graphics in. I'm smart enough to open it up in NDStool and extract the files, but that gives me a whole crapload of files which make semi-sense to me. I'm not sure how to modify the graphics in this, though. Can someone lend a hand?
The format used by the DS is identical to the format used by the GBA: 4bpp linear reverse-order.. If opening the data files in your tile editor of choice do nothing, try opening the NDS file itself. (This works for several commercial games, like Megaman ZX, but you need lots of available RAM)
Yeah, I'm seeing something... I'm not entirely sure what it is though. Gotta get the pallette right, I guess.
