Crystal Castles Arcade PCB Upgrade Compatibility for Original Atari Hardware
Confirm whether your original Atari Crystal Castles arcade PCB is compatible with the HighScoreSaves Free Play and High Score Save upgrade. The daughter-card kit installs at the 6502 processor location while keeping the original Atari game board and trackball-based hardware in service.
Choosing the Correct Crystal Castles Arcade PCB Upgrade
A Crystal Castles cabinet, marquee, control panel, or trackball does not by itself confirm compatibility. Vintage Atari cabinets may have been repaired, converted, or fitted with replacement hardware, so the actual arcade PCB should be identified before ordering.
The HighScoreSaves Crystal Castles upgrade is intended for documented compatible original Atari Crystal Castles arcade hardware. Confirm the game board, 6502 processor location, compatible CPU socket, and physical daughter-card clearance before beginning installation.

How the Crystal Castles 6502 Daughter-Card Installation Works
Installation begins by locating and carefully removing the original 6502 processor from the Crystal Castles PCB.
The compatible 6502 is installed on the HighScoreSaves daughter card with the correct orientation. The completed daughter-card assembly is then installed into the original 6502 CPU socket on the Atari PCB.
Before restoring cabinet power, verify Pin 1 orientation, processor alignment, socket condition, processor pins, daughter-card seating, and underside clearance. A riser or additional socket may be used when needed to provide sufficient clearance.

Crystal Castles PCB Compatibility FAQ
Which Crystal Castles arcade PCBs are compatible?
The upgrade is intended for documented compatible original Atari Crystal Castles arcade PCBs. The current installation guide states that the kit is specifically for a Crystal Castles PCB.
Which processor does the Crystal Castles kit require?
A 6502 processor is required. The compatible original 6502 may be removed from the Atari PCB and installed on the HighScoreSaves daughter card.
Why might a riser socket be needed?
The installation guide directs the installer to make sure nothing touches the underside of the daughter card. An additional or riser socket may be used when extra physical clearance is needed.
Can original Crystal Castles program ROMs be removed?
Yes. Program-ROM removal is optional under the documented ROM Saver configuration. Remove only the program ROMs identified by the current Crystal Castles installation guide.
Does the upgrade replace the original Atari Crystal Castles PCB?
No. The compatible original Atari PCB remains the underlying arcade platform. The daughter-card upgrade works with that hardware rather than replacing it with an emulation system or generic multicade.
