On the otherhand Mario bros for the NES has two separte entries (E-027-S-03750-A and E-027-S-00293-A). As the differences between the Mario Bros games are smaller then the two version of Ace Combat I wonder which way is the correct one.
That's because those two entries for Mario Bros. are actually different games. The first one you linked to is actually based off the FDS game Kakettekita Mario Bros while the other is based on the original 1983 release.
I've never heard that before! Very interesting!
I see that German release also has an Italian release linked to it. Is that really this second version.
If so its another to add to my get list as I'm going for the complete PAL A set
