Development by Jon Wilson (10yard)

How to Play

• Extract the contents of the dkbros zip file into a folder. It includes everything you need apart from the dkong.zip rom file.

• Place your dkong.zip into the wolf256\roms folder.

• Run the dkbros.exe program. This will set up a 2 player co-op Donkey Kong session in MAME.

• Press the start button to play

Refer to notes below for configuring the controls.

Features

• 2 players are controlled independently in the same game.

• Each player gets their own hammers, and they can be smashed together

• The last player to take a hammer gets barrel control and retains control until the other player takes a hammer. The barrels change colour when P2 has the steering.

• Pulling rivets is fun with 2 players sharing the task. The fireballs spawn in a calculated safe position for both players.

• If one player completes the stage then both players complete the stage together but the player completing the stage gets the bonus points - unless you finish exactly at the same time.

• Both players accrue points independently but there is a combined score displayed in the centre.

• If one player dies then both players die.

• There are 7 lives shared between both players.
