      I’m looking to dial in some optimal PSP settings. I’ve calculated some optimal timings based on hooking up my PSP to an oscilloscope, and am able to get a nice picture when in the main menu.

      Unfortunately however, the PSP letterboxes games. If I treat the letterboxed area as H./V. frontporch and backporch, I’ve calculated what the correct H/V. Active and H/V. Backporch should be. Unfortunately, the V. Backporch setting doesn’t go high enough (max is 63, I want 134). Is it possible to increase that limit?

      Here is my timing measurements, along with the calculations with the resulting OSSC settings.

        Realized there’s a dedicated board for feature requests. I’ve reposted this there.
