There may be a pattern for how files are stored and accessed. At the start of each sector, after the CD-XA header, if the sector is the start of a new file, there will be 16-bytes in front of it first. First 4-bytes with a random number. Then a single byte which represents how many sectors this file will occupy. The rest is zeroed out. With this, I was able to write a program that would go sector-by-sector looking for this header than matched. I was able to extract 1,049 background images in full.
