I did not see the error because I let cmpro update the old dat instance while importing. Yoshizuki used to reference his own nes.xml and shares it in the archive, but it did not always include the EOF condition... You can use Roman's which is provided with every cmpro install if you already have it. Ignore the error and set whateve ryou have in the Headers path settings area. Naming it "nongoodnes.xml" is risky, since it is very close to the full name of the set.
