[QUOTE="slidelljohn, post: 89, member: 504"] I cant give any advice for how to do this on the nes but I can tell you what I do when I run into these situations on the snes. Usually when you cant find the graphics in the rom then the graphics are compressed. What I do is find where the graphics are in vram and then I will trace the code backwards to see how it got into vram. Once I figure out how it got into vram then Ill be able to read the asm that is doing the decompression and I document everything about the decompression so I will fully understand the format. Once the compression format is fully understood then I would write a compressor to compress the edited graphics. Seems like the process should be similar for the nes. Now if you are doing something like restoring graphics that were in a Japanese game and taken out in say a north american version of the same game then all you would need to do is find the compressed graphics data and transfer it from one rom to the other.
