The second part is correct, the first part also but it can also be done by
simply going to screen 8.
The selection of screens >9 is so simple that it wasn't worth a new
BIOS-call. And since the v9958 is standarized, it will always be (upwards)
compatible.
So Basic simply does this to go to screen 8:
SCREEN 8
VDP(25)=8
I don't know this for sure, 'cause I haven't looked it up, but I think it's
this way.
Anyways both will work.
