Have you tried playing with the Integer Scale Axis setting? You might not get the perfect exact aspect ratio but maybe you'll be able to get something that looks much better than square pixels
When you set it to Y+X it will integer scale both axes separately to try to get as close to the correct aspect ratio as possible, but still only scaling in integers
For example on my 1440p display Y+X scales Street Fighter II x5 horizontally but x6 vertically. It's not the exact intended aspect ratio but it's way better than square pixels for this game
