Me again, buggin'.
Reporting that the "Demo Version contained in Sigma RealMagic Demo CD - ISO Demo 460MB (uploaded by mklgw1985)"
and the "Sigma RealMagic Version - ISO Demo 198MB (uploaded by mklgw1985)" links at that game post are now ex-links.
4Shared says: "The file link that you requested is not valid."
Cheers!
