Why this title

Why collectors care

The cultural context, the production lineage, the place this artifact holds in its console's history.

eleased by Konami in February 1988 for the NES, Contra ported the brutal-difficulty arcade run-and-gun to home consoles. The Konami Code (↑↑↓↓←→←→BA) — entered on the title screen to grant thirty lives — became one of the most famous cheat codes in gaming history and shipped first inside this cartridge.

Contra's 1988 Konami first print sits at the heart of the late-Black-Box / early-hangtab transition. The H-tab variant is the canonical first-print indicator. Sealed WATA 9.4 A+ trades $2,000–6,500; the Konami 1988 packaging (pre-Player's Choice and pre-Game of the Year reprints) is the structurally scarce variant.
