Rally-X & New Rally-X Kit Compatibility & Comparison
Compare two Rally-X high score save kit options for documented compatible original Namco Rally-X arcade hardware. Both the Lite and Multigame kits support Rally X and New Rally X, but they use different hardware configurations and installation methods.
Rally-X Lite vs. Rally-X Multigame
Both HighScoreSaves Rally-X upgrades are intended for documented compatible original Namco Rally-X arcade PCBs and support both Rally X and New Rally X.
The main difference is not the number of games. It is the hardware and installation approach used by each kit. Choosing the correct Rally-X high score save kit therefore depends on the original PCB configuration and the type of installation you prefer.
Rally-X Kit Comparison
| Hardware / Installation | Rally-X Lite Kit | Rally-X Multigame Kit |
|---|---|---|
| Supported Games | Rally X and New Rally X | Rally X and New Rally X |
| Original PCB | Documented compatible original Namco Rally-X PCB | Documented compatible original Namco Rally-X PCB |
| Z80 Requirement | Compatible Z80 at a compatible 40-pin socket | Compatible Z80 at a compatible 40-pin socket |
| Primary Hardware Approach | Compact Z80 daughter-card upgrade | Z80 daughter card plus additional supported graphics and color hardware |
| Color Hardware | Uses the original PCB color PROMs | Uses additional supported color hardware |
| Graphics Hardware | No additional graphics hardware described for the Lite configuration | Additional supported graphics hardware installed at documented locations |
| GFX ROM Setting | No Multikit GFX ROM setting described | Supported GFX ROM option must be set to the Multikit configuration after installation |
Rally-X Lite Hardware Approach
The Lite version uses a compact daughter card installed at the documented Z80 processor location.
The original PCB color PROMs remain in use, so the existing Rally-X PCB color hardware continues to provide the supported color information.
Rally-X Multigame Hardware Approach
The Multigame version uses the Z80 daughter card together with additional supported graphics and color components installed at documented locations on the Rally-X PCB stack.
After installation, the supported GFX ROM option must be configured for the Multikit so the graphics hardware is mapped correctly.
Z80 Processor and Socket Requirements
Original Namco PCB Upgrade vs. Replacement Hardware
Both Rally-X kits are designed around compatible original arcade PCB hardware. They are not intended to replace the game board with a generic multicade, JAMMA replacement board, reproduction PCB, or software-emulation platform.
The original Rally-X PCB remains the foundation of the cabinet. The choice between Lite and Multigame is therefore primarily about the supported hardware configuration and installation approach rather than choosing between Rally X and New Rally X.
Rally-X Pre-Order Checklist
After Confirming Compatibility
Once you have verified the original Rally-X PCB, compatible Z80 processor, 40-pin socket, and the hardware configuration you want to use, visit the individual product pages for complete feature information, current pricing, availability, Standard and Wi-Fi options, and ordering.
Rally-X Kit Compatibility FAQ
Do both kits support Rally X and New Rally X?
Yes. Both documented Rally-X upgrade options support Rally X and New Rally X.
What is the main difference between the Lite and Multigame kits?
The Lite kit uses a compact Z80 daughter-card configuration and retains the original PCB color PROMs. The Multigame kit uses additional supported graphics and color hardware beyond the Z80 daughter card.
Do both kits require a Z80 processor?
Yes. Both require a compatible Z80 processor at the documented processor location.
Does the Z80 need to be socketed?
Yes. The Z80 processor location must use a compatible 40-pin socket before either daughter-card configuration can be installed.
Does the Lite kit use the original color PROMs?
Yes. The documented Lite configuration continues to use the original PCB color PROM hardware.
Does the Multigame kit require additional setup?
Yes. Its documented installation includes additional graphics and color hardware, and the supported GFX ROM option must be configured for the Multikit after installation.
