I did a few more polishing runs and got more detailed images of the internal logic of the SCK pad.

Did you open a DMG CPU A chip as well? Or what revisions do you refer to?

ogamespec commented 4 days ago

No, I'm using https://siliconpr0n.org/map/nintendo/dmg-cpu-a/ But I'm "putting up" the polish from Revision B to find the differences between the revisions at the same time :-)
