Jerky Picture & Colour - Dreamcast Self Boot Backups

[bpaddy]

i'm having a problem with some of my dreamcast backups. they load ok but the picture is jerky and the colours flicker?!?

some backups and all originals work fine tho! could this be a refresh rate prob 50hz/60hz??

any ideas??

Yes, might be.

Which games do that ?
Did you check for a patch on DC Copy World ?

I got a big bundle of games on ebay originals & backups. Some of the backups like Soul Calibur, Dead or Alive 2, 18 wheeler are all jerky.

The games run perfectly otherwise but the picture continually jerks and the colours flickers red & yellow......

Would they run better on a tv that can handle 60hz???

Maybe...

Do you have a PAL or NTSC DC and TV ?
