Quick update: Marshall asked me to do some more analog testing, so I drove 90+ minutes to meet with one of the group-buy participants and test my HW2 unit with his Framemeister. Marshall probably assumed I owned one. I also did some more testing with my OSSC. He considered a small change to the install procedure, disconnecting the N64's CSYNC signal from the multiout connector and using sync from the UltraHDMI HW2 DAC. The UltraHDMI HW2 DAC is slightly faster (lower latency) than Nintendo's DAC. The screen can be shifted by a few pixel columns depending on where your TV or scaler is pulling the sync signal. Currently, pulling sync from composite, luma, or CSYNC will get the slightly delayed sync from the N64's original DAC. Using RGsB (sync-on-green) or Y/Pb/Pr (component) will get sync from the UltraHDMI DAC.
I would never notice the slight shift in the image if I didn't take pictures and compare:
https://imgur.com/a/9AGHxbX- Marshall's high-quality RGC brand cable is labeled "CSYNC," but apparently gets sync from luma.
- I have some cheap Chinese EuroSCART cables that get sync from composite.
- If I recall correctly, HD RetroVision cables pull sync from composite.
For most people it's probably not worth bothering with an extra step for CSYNC if most SCART cables still won't use it.
Ichinisan- Tested with a friend's Framemeister today.
- Works.
- I don't know anything about optimizing settings for Framemeister, but it works.
Marshall H- ah cool!
- does sync-on-green RGB work with the framemeister?
- I tried that with a Dell monitor i ahve that supports SOG for my SGI machines
- If you can think of anything else we ned to watch out for, let me know
- But i think we should get on shipping
- The only thing I don't know how to handle is the CSYNC line generated by the board, compared to the N64's csync
- they are the same, but one is a bit delayed (the original one)
- You can see this if you have a PVM, and wire up the original n64's CSYNC.
- If you then switch between Component/RSoGB and then external sync, you will see a horizontal shift
Ichinisan- Didn't get to try sync on green. Maybe I'll be near there again some time (about 1.5 hours away from here).
- HD RetroVision RGB to Y/Pb/Pr cable gets sync from composite. Would that also be delayed?
- I can probably test sync-on-green with my OSSC
- I'll try that
Marshall H- if anything uses sync on composite, it will be slightly delayed versus the ultrahdmi dac
- since the dac is actually faster
Later I tested RGsB with my OSSC and updated the IMGUR album.
Marshall said he's more interested in finishing these, but I haven't heard anything since that a couple weeks ago.
My friend is re-opening his restaurant during COVID, so helping him has taken a lot of my time recently. He will hire someone soon and won't need my help as often. I'm still working through email, but I'm much closer to being caught-up. One participant created a Google form that might help to automate the process. I hope to implement that soon!
I'll be back to the thread soon. Working late on email tonight...
