You know, Ruud, I see those little 2-byte hex numbers on roms fairly 
often, even official ones.  Usually when there are printed stickers on 
the eproms.

I always assumed they were a checksum, or crc or something. However, I 
ran the binary you gave us through a program that spits out every single 
kind of hash, checksum, or crc imaginable, and that binary did not 
produce $697b for any of them.  So unless there is some calculation I'm 
not aware of, I have to say that I don't know either.
