I can't get the double pixel mode working. Mapping the C128 has a small BASIC program that is supposed to showcase it, but the monitor doesn't like it and will not sync.
It looks wrong because it doesn't modify the horizontal sync width or blanking start and end. My own test that takes those into account as well doesn't work either. Has anyone of you managed to get the mode running?
10 WR=DEC("CDCC"):RR=DEC("CDDA")
20 SYS WR,63,0:SYS WR,40,1:SYS WR,55,2
30 SYS RR,,25:RREG A:SYS WR, (A OR 16),25
40 SYS WR,(8*16)+9,22
50 SYS WR,40,27
60 POKE 238,39
