One of the lesser-known versions of Contra developed for home computers, this version for IBM PC and compatibles (courtesy of the oddly named Banana Development) was actually published in the U.S. alongside the Commodore 64 version by Konami themselves. Not a particularly good conversion, due to its faulty controls, hence why it never went on to become a classic like the NES version.

Unused Quit Text

This is supposed to be shown when quitting the game, but it's rendered as black text on a black background. Therefore, it isn't visible without hacking the game.
