That's what I thought. Both games are NTSC-Versions (at least I think so), and I'm running them on a NTSC-Console. So I fear the reason they refuse to work has to do with the RGB-cable (which I have to use). But as there seems to be no RGB-Fix, I'm gonna try your patcher and look after the string you told me.
I'm gonna check this later (burning online turned out not to be such a great idea

) and let you know if it worked.
Till then, BIG THANX for your help
