Solved Missile command - crashing - ideas? When high score entered

[Sbdesign]

Hi,
Just had mc pcb fixed.

I soak tested which was totally fine
But now I realised that if I get a high score and put In Initials It instantly crashes after it.

Anyone know what could cause this? Or likely?

Or if a high score kit would eliminate it?
Appreciated thanks.

If it crashes at the same point then most likely a ROM issue.

As the Braze kit has its own ROM it may stop the game from crashing, and will also save the high scores.

I’ll give it a go
I have a clean board that needs repair so if I knew which rom it could be I could try swapping it out

UPDATE: put braze kit and ok!
