Skies of Arcadia NTSC/PAL patch

I burnt SoA NTSC-version and tried to play it on my PAL-dreamcast. The screen was all screwed up so it was totally unplayable. I #####ed on dccopyworld but I couldn't find a patch to make it playable on a PAL-dreamcast. Does it exist? Or is it just a bad burn? And can I patch a NRG-archive?

I'll leave you alone now to think about an answer on my questions

Thank in advance,
Jan
