I could just keep quiet here, but I'll apologize :)  I was one of the guys
who did some testing on that a long while back.  I concluded that WSYNC
did in fact need one or two extra clocks.  Unfortunately, it turned out
that I had made a mistake in my test code.  My playfield kernel had a
WSYNC, then a long string of NOPs, then DEC and BNE.  Problem was, the BNE
was branching across a page boundary, which uses one extra cycle, and I
didn't realize this was happening until a long while later... :(
