Choosing the Correct Donkey Kong Rearranged 3DKJr Configuration

The HighScoreSaves Donkey Kong Rearranged 3DKJr Multigame Free Play and High Score Save Kit is the Donkey Kong Jr. installation configuration of the shared 3DK/3DKJr Rearranged multigame product. The 3DKJr configuration is intended for documented compatible original Nintendo Donkey Kong Jr. two-board PCB stacks.

The configuration is determined by the original arcade PCB used for installation. Choose 3DKJr for compatible Donkey Kong Jr. two-board hardware. The separate 3DK configuration is used when installing the same Rearranged multigame system on compatible original Donkey Kong two-board hardware.

Original Nintendo Donkey Kong Jr. PCB Compatibility

Original Nintendo Two-Board Hardware The 3DKJr configuration installs on documented compatible original Nintendo Donkey Kong Jr. two-board PCB stacks. Installation requires access to both the CPU PCB and video PCB.
DJR1-Series Donkey Kong Jr. Boards The current 3DKJr installation guide illustrates compatible Donkey Kong Jr. hardware using DJR1-xx video and CPU PCBs. Board revision markings may vary, so the complete installation requirements should be verified before ordering.
3DK and 3DKJr Are Installation Configurations Select 3DKJr for compatible original Donkey Kong Jr. two-board hardware. Select 3DK for compatible original Donkey Kong two-board hardware. The supported Rearranged game collection is the same; the configuration identifies the original Nintendo PCB used for installation.

How the 3DKJr Rearranged Hardware Installation Works

The 3DKJr system uses several daughterboards installed across the original Nintendo CPU and video PCBs. This is a more involved installation than a single Z80 daughter-card upgrade and requires access to multiple documented CPU, EPROM, and PROM locations.

The original PCB's Z80 is removed but is not reused because the 3DKJr main daughterboard already includes its own Z80 processor. The original compatible 8035 processor is removed from the Nintendo CPU PCB and transferred to the empty 8035 socket on the main daughterboard.

Additional daughterboards install at documented locations on the original CPU and video boards. Component orientation, socket condition, grabber-wire connections, ribbon-cable placement, and daughterboard seating should all be checked against the current installation guide before power is restored.

3DKJr Pre-Order Compatibility Checklist

1. Confirm a Donkey Kong Jr. Two-Board PCB Stack Verify that the cabinet contains documented compatible original Nintendo Donkey Kong Jr. two-board hardware. Use the separate 3DK configuration for compatible original Donkey Kong two-board hardware.
2. Confirm the Original PCB Works Make sure the original Donkey Kong Jr. board stack is fully operational before beginning installation. Existing PCB problems should be corrected before adding the multigame system.
3. Inspect the Z80 and 8035 Locations The 3DKJr kit supplies its own Z80, while the original compatible 8035 is transferred to the main daughterboard. Confirm that the required processor locations are suitable for the documented installation.
4. Inspect EPROM and PROM Locations The 3DKJr installation uses multiple EPROM and PROM locations across the original video and CPU PCBs. Required component locations must be compatible and properly socketed.
5. Review the 3DKJr Guide Before Ordering Review the complete 3DKJr installation guide before removing processors, EPROMs, PROMs, separating the two-board stack, or fitting any daughterboards.

3DKJr CPU and Video PCB Installation Requirements

Video PCB The current guide begins on the DJR1-xx video PCB by removing the four EPROMs at 7C, 7D, 7E, and 7F and installing the matching daughterboard. Additional documented video-board installation points include the EPROMs at 3N and 3P and the PROM at 2N.
CPU PCB On the DJR1-xx CPU PCB, the original Z80 is removed because the main Rearranged daughterboard already contains a Z80. The original compatible 8035 is transferred from the Nintendo PCB to the main daughterboard.
Additional CPU-Board Locations The current 3DKJr guide also documents installation using the original CPU-board locations associated with 3H, 2F, and 2E before the final ribbon cable connects the daughterboards across the two-board stack.
Socket Condition Matters No soldering is normally required when every required installation location is already correctly socketed. If a required CPU, EPROM, or PROM location is soldered directly to the original PCB, the appropriate socket must be professionally installed before the kit can be fitted.

After Confirming 3DKJr PCB Compatibility

Once the original Nintendo Donkey Kong Jr. two-board PCB stack, processor locations, component sockets, and installation requirements have been confirmed, use the individual product page for the complete game collection, Standard and Wi-Fi choices, included components, current pricing, options, and ordering information.

This category is intended primarily to determine whether original Donkey Kong Jr. hardware is suitable for the HighScoreSaves Donkey Kong Rearranged 3DKJr Multigame Free Play and High Score Save Kit before an order is placed.
