Donkey Kong / Donkey Kong Junior    High Score Save Kit -- Plus Extras!

A simple to install high score save kit that permanently remembers the top 5 scores and initials for Donkey Kong or Donkey Kong Junior. Plus many extras features such as deluxe Freeplay, attract mode sound, powerup Selftest, and on-screen Settings.

Installs in minutes! No special wiring or soldering is typically required. Simply remove the Z80 chip from your DK/DKjr CPU board, insert this Z80 CPU chip into the daughter card (pictured right) and then plug the daughter card into the vacated Z80 socket on the CPU board. Thats it! Detailed installation instructions provided online here.

Note: Since releasing this product, I have found out that some 4-boardset style DK games unfortantely have the Z80 chip soldered to the CPU board. If you have a 4-boardset style DK game, please examine your boardset prior to ordering and read over in detail the install guide, as installation will not be as easy in this case.
