It says that is a invalid application win32. I tried to oppen the breat of the NES's exe with notepad and scrolling down, at the end says:
type="win32"
name="Microsoft.Windows.Common-Controls"
version="6.0.0.0"
processorArchitecture="x86" ( maybe this sould be saved as x32)
publicKeyToken="6595b64144ccf1df"
language="*"
And below says:
<compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1">
<application>
<!--This Id value indicates the application supports Windows Vista/Server 2008 functionality -->

<supportedOS Id="{8e0f7a12-bfb3-4fe8-b9a5-48fd50a15a9a}"/>
</application>
</compatibility>
So, there isn't compatibility for win xp, just windows vista, but not mine. To run in XP, should be an entry which says:
<!--This Id value indicates the application supports Windows XP functionality -->
<supportedOS Id="{algorithm code}"/>
PS: I tried to put all compatibility modes & set the exe as x32, but it doesn't work, cause i don't know which would be the algorithm code in the parentesis.
