Just to say I've been creating a Doncaster Rovers Video Archive over the past few months; you can find it here: http://awayonsaturday.blogspot.com/2020/04/doncaster-rovers-video-archive-2013.html.
If there's any footage of Oldham vs Doncaster games you need, feel free to take it, download it, link it to this forum - whatever is easiest for you.
If footage from any of the outstanding games turn up, I'll give you a shout.
