Koko Adventure is a South Korean unlicensed game. An American release titled Buzz and Waldog was planned but canceled for unknown reasons. It has a lot of assets stolen from other games which isn't too common for pirates.

The game itself is... underwhelming. For each level, you have to collect a certain amount of keys under a restrictive time limit. In defense, the game has solid graphics, music, and gameplay considering that it's a pirate.

MMC3 conversion of the unlincensed, korean game Ko Ko Eo Deu Ben Ce which is also known as Buzz & Waldog in the USA.

This game was slightly different than the prototype of Buzz & Waldog.

EDIT: Since I accidentally messed up the life counter, to fix this, go to hex address x19169 and change E9 to A2
