I see there are some reports of the game glitching up in Nestopia; specifically, that the Start button is pressed even though it isn’t.
I don’t really know where the issue lies, if it’s Nestopia or D-Pad Hero. (Did anyone try it on real hardware yet? I guess that would be the ultimate test.) We’ve tested D-Pad Hero with version 1.3.9 on Windows and it works fine. It also works fine with Nestopia 1.3.6 on Mac OS X. I have verified that it’s glitching up in Nestopia 1.4.1 on OS X, though. If you could post the OS & version where the game acts weirdly, that would be helpful, thanks.
