Hi RetroACTIVE,
I'm afraid you didn't copy the monitor_specs properly, as I can see in your logs (16000-17000 and 18300-19000 ranges are missing). Please double check it, specially the subindex part. Make sure there's no duplicated label for any monitor_specs. Fortunately it's been useful to discover the right range for the 288-lines games (pacman, dspirit).
I've done some additional changes, try the same games with these new settings:
monitor_specs0 15625-15900, 40-80, 2.187, 4.688, 6.719, 0.190, 0.191, 1.018, 0, 0, 248, 448
monitor_specs1 16000-17000, 58-80, 2.187, 4.688, 6.719, 0.190, 0.191, 1.018, 0, 0, 256, 448
monitor_specs2 18300-18800, 40-58, 8.300, 2.750, 9.000, 0.190, 0.191, 1.018, 0, 0, 280, 448
