weird flickering

[myoriginalname]

Hi everyone, I'm having issues when trying to run digimon world 4 I get a horrible flickering on the image. The weird thing is that when I captured a screenshot to my surprise, the picture wouldn't show this annoying "effect".
I'm assuming it has something to do with my old NVidia 7300 gt, however I don't know for sure, so i was just wondering if anyone else has gone through the same problem as me.

Does it flicker gray every other frame? Harry Potter COS does the same thing. It just looks like it's random because of a lack of vsync. My guess is it's just an accuracy of emulation issue, since the real GCN obviously didn't do that. I'll have to check out Digimon, see if it's the same thing… But I don't have the actual game so I can't rip it. Time to go to Game Force.
