Seibu SPI mobo/ pcb on 31 khz monitor

Post by spikehead »

Both SPI based games (VP 1 Japanese) and Raiden II flicker or freeze when I try to run them on a Sanwa 31 khz monitor using this scaler:

Other jamma beasd games run fine if the resolution is set to 640*480.

I read somewhere that the Seibu boards have a quirky refresh rate and might cause problems. Am I missing something concerning the scaler or do I need other devices to make Seibu games run on the above mentioned monitor?

Thanks for your help.
