Something similar but more simpler: I made some python scripts that inputs images I want to show up on the NES and outputs a grayscale image that I can copy & paste to YY-CHR to output a binary that I can dump to NES binary (I could probably replace YY-CHR entirely and dump a binary myself). The intention was the artist could put all the things that we want to show in the background layer and it would give us a tile map. You could also feed it an existing tile map & color palette and it would give you updated version of them to show the new image. It was also dumping a RLE data if you want to show a specific image on the screen. For example you could grab a screen shot from SMB, feed it to our script and it would give you RLE & tiles needed to feed it to NES It worked well for me & an artist I worked with on a game jam. The artist drew the background for the main game and were were able to use it in the game. I was super happy about it
