I'm back with more info. Here is a great link for the release dates. It shows DK Jr Math as 10/85 and Star Tropics as 12/90.

Also, I have a little info on an interesting find. I have a gold seal, non-Rev-A, non-hangtag. Inside is the 3-screw version without security screws.
Also, I'll continue to check my hangtag boxes.
I have every black box with a hangtag as well as Capcom's first 5 releases: Ghosts 'N Goblins, 1942, Commando, Section Z, and Trojan.
I also have Spy Hunter and Burgertime and some others, but will have to check.
