I see couriersud sent in an update/fix.
- Fixfreq.c: Don't process hsyncs while we are vsyncing. Fixes video jitter/jumps. -
I agree it likely does happen with real hardware (Pong pcb and black/white tv monitor), but not to the visible extent as what happens when playing pong in MAME .151
If that visual effect in .151 happened with actual Pong and other pong clones hardware back then, that might have been enough to drive folks back to spending money on playing pinball and electro-mechanical games during mid 1970s which would have made Midway, Allied Leisure, and Chicago Coins very happy since they had that market well covered.
As long as I could find and play a Chicago Coins Flying Tigers cab, that made my 1970s era arcade day experience a good one. :-)
