(Edit: Disregard) NES Games "Double Strike" & "Twin Eagle" are the same game.

[Fugus]

The original game was "Twin Eagle" https://gamesdb.launchbox-app.com/games/details/2046

It had an official release called "Double Strike" https://gamesdb.launchbox-app.com/games/details/1635 with minor changes.

There are 2 entries in it but with lots of media, not sure how to handle that myself. The Double Strike entry appears to be the more complete of the two but Twin Eagle was its original name.

Edit: Nevermind, instead attempting to add this as the bottom of the Double Strike description

"This unlicensed game from Sachen (for this release under the Joy Van brand) originated in Taiwan as 双鷹 (pronounced Shuāng Yīng and translated by Google as 'Double Eagle') in 1989 and also released in Japan in 1989 as 'Twin Eagle'.

Despite the identical title and shared release year, this is a completely different game from the licensed game by SETA Corporation called Twin Eagle published in 1989 by Romstar Inc. in the US and published in 1991 by Visco Corporation for the Family Computer in Japan."
