Fraid not off the top of my head. There a tag with a copyright date or anything like that? If it only says "©1984 Columbia Pictures" instead of "©1986 CPT Holdings" or something like that, it might narrow it down a little. Or it might not--being a fairly direct movie carryover, it could still have the 1984 date.
Sad to say, your best chance might be to post about it on GBFans.
Also, moved to one of the Ghostbusters forums, since it is a GB topic.
