>Can I trust z26 (2.) here?
Yes.
Running the following on my Supercharger:
sta WSYNC
lda #1
sta VDELP0
lda #255
sta GRP0
lda #0
sta VDELP0
lda #128+32+8+2
sta GRP0
lda #1
sta VDELP0
sta WSYNC
sta WSYNC
sta WSYNC
sta WSYNC
sta WSYNC
sta WSYNC
sta WSYNC
sta WSYNC
sta WSYNC
sta WSYNC
Displays nothing (In a standard kernal type loop, having set COLUP0 and positioned player0 with RESP0. And just to be sure, commenting out the VDELP0 references DOES produce a vertical bar)
It's like a primitive double buffering...
Wow.
