Play Buzz & Waldog (Unl) (Proto) Online

Summary

Koko Adventure is a quirky platformer that first appeared on the Famicom in 1993, crafted by the South Korean studio Open Corp. It stands out as one of the very few NES‑era titles born outside Japan or the United States, giving it a rare cross‑cultural flavor. When the game was slated for an American release, it was renamed Buzz & Waldog, though that version never officially hit shelves. The title’s playful design and off‑beat aesthetic have turned it into a collector’s curiosity, especially among retro enthusiasts who appreciate its unusual origin story. Even without a wide launch, the game’s legacy lives on through hobbyist translations and the occasional nostalgic showcase.
