Sorry if this has been mentioned, but is the UltraHDMI firmware still in development? Deinterlacing seems really spotty on a few games that I've tried it with. Also, kinda curious if it's possible to implement a 240p output over HDMI.

Thanks for the help. Good to know!

The reason I brought it up is that I think the smooth scaling on the RetroTink2x looks pretty good, and I would wager that the OSSC Pro will have something similar. Seeing as it has an HDMI input, I imagined a scenario where I could feed my UltraHDMI at 240p in to the OSSC Pro to get a smoothed 1080p image out of the combination of the two. Problem is that I don't think you can smooth out content that has already been line doubled.

I wonder if RetroTink-style smoothing could be done internally on the UltraHDMI... I mean, it's still the N64 so it'd kinda be like making a silk purse out of a sow's ear, but it's still an improvement some of the time.

A quick update: Marshall just received flex PCBs from the factory in China. This is the secondary flex PCB, which carries analog signals from UltraHDMI's DAC module to the N64 AV multi-out connector. These will be paired with the small batch of final UltraHDMI HW2 boards he made in a test production in September (several dozen units). The December 31 order of 150 UltraHDMI units is still in-production after many delays with the factory in China.

There's a minor issue with the flex PCBs that just arrived. Marshall believes he can fix them manually with a hole-punch.

Quote:

- finally got the flexes
- main flex seems fine
- the analog flex was produced without the proper holes

- got some 1.25/1.5mm hole punches on the way

With some small holes in those circular pads, the pins of the N64's AV multi-out will poke through so the flex can be soldered to the existing pins.

Thanks for the update. Will that small batch of several dozen be going to round 7 pre-orders?

Yes. The list is sorted by the date+time I received payment for the kit. I will assign the kits to group-buy participants once I receive and test all of them.

Ichinisan,

This is getting exciting. Not sure if my messages are showing up on the forum. I just signed up for the forum and wanted to see if you got my email request on the 14th for x5 kits. Please let me know and where i can submit payment.
Thank you and have a great day.

Has it been disclosed yet whether the analogue output is original modes, post-processed, or selectable?

I too would like to know this. It would also be good to know if the analog output resolution can be set independently of the HDMI output (e.g. 480p HDMI with 240p Analog)

Got an answer from Marshall:

Ichinisan
- asking if the Y/Pb/Pr output supports 480p / 720p / etc.
- I assume it's native resolution only (240p / 480i).

Marshall
- yeah it is native only. the only processing is gamma and deblur

Hi Ichinisan,

how can I reach you for pre ordering 2 ultrahdmi kits?

After a long internet search I just found this forum :) I just registered here but can't find a button to send you a private message for my pre order.

Best,
magnus

I’d love to know if it’s possible for the ultrahdmi to output 240p120.

His email address (along with all the information he needs from you when you make the order) is all in the first post of this thread!

I believe that would be within the bandwidth limitations, but why? It's not like the N64 can render at 120fps; all it would be doing is repeating frames and introducing more display lag than necessary.

For the same reason SWISS does. Scanlines on a 31kHz CRT.

Well, the reason there was to reduce end-to-end latency.
