External Synchronization: Difference between revisions

Revision as of 19:34, 31 May 2023

EXTSYNC is a mysterious signal that is sent to pin 26 of PPU1. It is tied to VCC. One theory is that it was supposed to allow the PPU to not have to generate the TV synchronization signals itself and have them input into it instead.
