What's the point with having different flags for single screen $2000 and single screen $2400 in UNIF? I must have missed something cause it just seems so stupid. 
Some mappers allow games to select either one of those regions for single-screen mirroring (After Burner 2 (J)?).
Toss your four-directional scrolling screen in the lower nametable and the status bar in the upper nametable, and then use the mapper to switch between them.
But for the UNIF mapper chunk, which describes what is hardwired, I don't exactly see much of a point.

Yes, many mappers switch between the two, but I was referring to the UNIF mirroring flag.
I was just curious whether there was a purpose with this, but I guess somebody just made a mistake.

I guess it was just an anal-retentive desire to document whether the original cart hardwires GND or VCC to CIRAM A10.
