Rally-X & New Rally-X Arcade PCB Upgrades for Original Namco Hardware
Compare HighScoreSaves Rally-X upgrade options for compatible original Namco arcade PCBs. Both the Rally X | New Rally X Lite Kit and Rally X | New Rally X Multigame Kit support Rally X and New Rally X, but they use different hardware approaches and installation configurations.
These are original-PCB upgrades rather than replacement JAMMA boards, reproduction PCBs, generic multicade systems, or software-emulation platforms. This category is intended to help collectors, restorers, and operators compare the two approaches, verify Z80 compatibility, and choose the appropriate kit before ordering.
Compare Rally-X Lite and Rally-X Multigame Upgrades
Rally X | New Rally X Lite Kit
The Lite kit uses a compact daughter card installed at the Z80 processor location. It supports both Rally X and New Rally X while continuing to use the original PCB color PROMs for the game's color palette.
Rally X | New Rally X Multigame Kit
The Multigame kit also supports Rally X and New Rally X, but its installation uses additional graphics and color hardware in addition to the Z80 daughter card. The Multigame installation also requires the supported GFX ROM setting to be configured for the multikit after installation.
Rally X | New Rally X Lite Kit Installation Guide
Rally X | New Rally X Multigame Kit Installation Guide
Before ordering, verify that your cabinet contains a documented compatible original Rally-X PCB and review the installation guide for the kit you are considering. Both upgrades require a compatible Z80 processor location.
Rally-X Hardware and Z80 Compatibility
Both HighScoreSaves Rally-X upgrade options install on documented compatible original Rally-X arcade hardware and require access to the Z80 processor location. The Z80 must use a compatible 40-pin socket before the daughter card can be installed.
- Designed for documented compatible original Namco Rally-X arcade PCBs
- Both upgrade options support Rally X and New Rally X
- Both require a compatible Z80 processor
- The Z80 processor location must use a compatible 40-pin socket
- The Lite kit retains the PCB's original color PROMs
- The Multigame kit installs additional supported graphics and color hardware beyond the Z80 daughter card
Rally X | New Rally X Lite Free Play and High Score Save Kit
Rally X | New Rally X Multigame Free Play and High Score Save Kit
HighScoreSaves designs and supports Rally-X and New Rally-X upgrades for compatible original Namco Rally-X arcade PCBs using Z80 processor hardware.
Rally-X Lite vs. Rally-X Multigame: Understanding the Difference
Both HighScoreSaves Rally-X upgrades allow compatible original Rally-X hardware to run Rally X and New Rally X. The primary difference is not the number of supported games; it is how each kit interfaces with the original PCB hardware.
Rally-X Lite Hardware Approach
The Lite version is a compact Z80 daughter-card upgrade. The original PCB color PROMs remain in use, so the board's existing PROM hardware continues to provide the supported color information. This makes the Lite kit distinct from the larger Multigame hardware configuration even though both kits provide Rally X and New Rally X.
Rally-X Multigame Hardware Approach
The Multigame version uses the Z80 daughter card together with additional graphics and color components installed at documented locations on the Rally-X PCB stack. After installation, the supported GFX ROM option must be set to the Multikit configuration so the graphics hardware is mapped correctly.
Original Namco PCB Upgrade vs. Replacement Hardware
Both Rally-X kits are designed around compatible original arcade PCB hardware. They do not replace the game board with a generic multicade, reproduction PCB, JAMMA replacement board, or software-emulation platform.
For an original-hardware restoration, this approach keeps the Rally-X PCB and its dedicated arcade hardware in service while adding the supported upgrade. The choice between Lite and Multigame therefore comes down primarily to the supported hardware configuration and installation approach rather than simply choosing between Rally X and New Rally X.
What to Check Before Choosing a Rally-X Kit
Rally-X boards may have been repaired, converted, or modified during decades of service, and more than one documented PCB style exists. Inspect the actual board installed in the cabinet before selecting an upgrade.
- Confirm that the cabinet contains a documented compatible original Rally-X arcade PCB
- Locate the Z80 processor on the PCB
- Confirm that a compatible Z80 processor is present or will be supplied with the kit
- Determine whether the Z80 is already installed in a compatible 40-pin socket
- For the Lite kit, inspect the original PCB color PROM hardware that remains in use
- For the Multigame kit, review the additional graphics and color component locations shown in its installation guide
- Compare your PCB layout with the appropriate installation guide before ordering
- Review the Rally-X Lite Installation Guide or Rally-X Multigame Installation Guide for the hardware configuration you are considering.
Choose the Rally-X Upgrade for Your Original PCB
After verifying your original Rally-X hardware, compare the Rally X | New Rally X Lite Kit and the Rally X | New Rally X Multigame Kit for current pricing, configuration choices, exact score-saving features, Standard and Wi-Fi options, and ordering.
