Yah of the remade stuff of yesterday FF4 was sheer awful in how they damaged it with certain tweaks, my fav and it disgusted me enough to sell it which took me weeks to do.
DQ4 I kept though as it was fantastic and I loved how the first 4/5 chapters were like MINI-RPGs where you played and did a story, then in time the stories all come together in big chapter 5 to work towards the end as a group.
DQ5 as it would take a good probably 30-40 hours to do I don't have time to invest in it, but I will in time, just can't now so I don't have it. But I will back what the others said in that time and again I've seen it listed by and far the best of the original Nintendo era titles.
