The PCB in question was sold 22 years ago, people weren't very good at documenting things 22 years ago compared to today.
It sounds like the guy dumped it back then, tried to emulate it, couldn't figure out this blitter / protection thing, and then gave up, until remembering it now and seeing nobody had submitted anything for it in that time. People wanting to emulate something start to finish, or otherwise submitting nothing, wasn't exactly uncommon back then (it still happens to a lesser extent today too unfortunately)
There are almost certainly a lot of people sitting on old dumps of PCBs they've long since sold. Some of these will be bad dumps, some of them will be good, some might already have been lost to rotting CD-ROMs or dead HDDs that haven't been checked in that time too. Many of the original PCBs have found their way back to Japan in that period and now cost a lot more than they did then if anything needs rechecking!
If you look at early dumps from the late 90s and early 2000s we actually ended up with a lot of prototypes dumped that nobody at the time even realised were prototypes. I'm actually quite surprised on my streams when Ozzyguy drops by to tell me certain games I'm playing were never even released. People just kinda assumed back then everything they had was common and that somebody else would get around to it one day if they didn't submit anything. The reality is, often it wasn't common at all.
