Donkey Kong Jr. High Score Save Kit Compatibility and Multigame Comparison

Donkey Kong Junior Remix Multigame Free Play and High Score Save Kit with Trainer
Choosing the Correct Donkey Kong Jr. High Score Save Kit
The HighScoreSaves Donkey Kong Jr. Free Play and High Score Save Kit category includes four different upgrade paths for compatible Donkey Kong Jr. arcade hardware. The correct choice depends on the PCB installed in the cabinet, the processor and socket configuration, and whether you want original gameplay, Remix content and training tools, or a larger Donkey Kong multigame system.
These products are not interchangeable simply because they all support Donkey Kong Jr. The standard HighScoreSaves and Braze kits, the John Kowalski Remix system, and the Donkey Kong Rearranged 3DKJr configuration have different hardware and installation requirements.

Donkey Kong Jr. Kit Compatibility FAQ
Do all four Donkey Kong Jr. kits support the same arcade hardware?
No. The standard HighScoreSaves and Braze kits are intended for documented compatible original Nintendo Donkey Kong Jr. hardware, Remix has broader documented board and processor support, and 3DKJr requires compatible original Nintendo two-board hardware.
Does 3DKJr work on every Donkey Kong Jr. PCB?
No. The 3DKJr configuration is intended for documented compatible original Nintendo Donkey Kong Jr. two-board PCB stacks.
Can Donkey Kong Jr. Remix work with an NEC D780C processor?
Supported Remix installations can include the NEC D780C and other documented compatible Z80-family processors. Verify the exact board and processor configuration with the current Remix installation guide.
Do the standard HighScoreSaves and Braze kits reuse the original Z80?
Yes. Both standard Donkey Kong Jr. upgrades use the original compatible Z80 processor from the game PCB.
Does Donkey Kong Jr. kit installation require soldering?
Not when every required processor and daughterboard installation location already has the correct socket. If a required component is soldered directly to the PCB, it must be properly removed and the appropriate socket installed before fitting the selected kit.
