I trying to make PSX CD image repacker for own needs. I need to make it to be free from third-party repackers.
This is the structure schema that I understand from the image.
Other repackers changes that ending bytes when something is repacked, so I need to do the same, but I don't even know what is that and what rules applies to it.
Some real data:
Most of time it looks like something compressed, but rarely is a lot of zeros and few non zero bytes.
