Just saw it on Zophar's domain. If you're like me, and can't get the best SNES emu ZSNES to work with XP, you should download the newest version of the second best emu out there for SNES.
There was also a new release of Zsnes not too long ago, and I didn't have any problems in XP with it. Try this also (v1.36):
http://www.zsnes.com
u should have no problems running either of those emulators on xp, double check the extraction of files, (although its hard to believe anyone could botch that up). what exactly is your error message?
BTW, i would stick with zsnes.
