The Pennsylvania (PA) return can be filed separately regardless of the filing status on the federal return. Either way you file (part year resident or nonresident), the PA tax will be the same because they have a flat rate of tax. And the full year will be considered for any type of tax forgiveness.
The state returns don't give you the option to enter dates in the middle of the year, so use a date that represents the number of months you worked in PA. In your case you worked in PA for 9.5 months.
You will not be able to answer "yes" that you and your spouse lived apart the last 6 months of the year. (Click the image attached to enlarge and view).
Because you were living in Wisconsin (WI) the last part of the year, you were living there during part of the last six months.
