Edited - ? of high score ranking on Cave arcade PCBs...

[PC Engine Fan X!]

I've noticed that on some Cave arcade PCB titles, even if you continue with one or two credits and score high enough to register your intials on the high score screen, the CPU allows this. But if you continue with a 3rd credit, you can't register your high score at this point. Why is this?

You might recall that this very same situation happens on some Psikyo arcade PCBs such as Strikers 1999/Strikers 1945 III PCB. ^_~
