Yea, I'm running XP. My netbook does run Nestopia fine, just not while CursorXP is enabled, I've stopped using it anyway.
I see you're running Win7, did you know that Microsoft has a free download that gives you WinXP mode for Win7? So you can run older software.
Here's the link:

And yes, thank you c0d3h4x0r for the update, well done!
