Dreamcast and snes rgb pvm sync issue

[Speedkingfox]

Hi guys. I seem to have an issue with using a dreamcast and snes (pal) with a pvm. Going through a powered up sync strike. The screen is rolling constantly. When hooked up to a ps2 , ps1 saturn , etc all are ok. Any advice would be great. Thanks

do you have one of these modified rgb cables for your snes? the console outputs pretty high voltage levels which need to be reduced in order to work with the sync strike.
don't know about the dreamcast though. i believe mine works fine witht he sync strike...

Not sure about modified. Bought via a web site who stated was pure rgb. Is there anything i need to change on the sync strike maybe.

nope. you can get a snes rgb cable that works with the syncstrike from the arcadeforge store though.

do you have a 15khz compatible vga box connected to your dreamcast that you use in conjunction with the syncstrike? if yes, that might be your problem.

Just a sync strike connected to a vga-component cable. Like i said the ps2/jag/md all work fine and the dc works great via vga,just not via the official sega rgb cable
