Contra (DOS)

Contra
Also known as: Gryzor (EU) Developer: Banana Development Publishers: Konami (US), Ocean (EU) Platform: DOS Released in US: 1988 Released in EU: 1988 This game has unused text. This game has a hidden level select.

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 US alongside the Commodore 64 version by Konami themselves.

Unfortunately, it's not a particularly good conversion due to its faulty controls.

Unseen Quit Text

While this is used when quitting the game, it's rendered as black text on a black background, making it impossible to see without hacking.
