I've been getting lots of emails and general interest in this. I'm looking into handling digital audio as well, so you need only the HDMI cable and nothing else. It will require yet another hardware revision.
I've been getting some feedback about the DVI port, some people don't use VGA anymore and just want a plain HDMI port. Email if you have an opinion about this...
This is not a plug and play board. Soldering is required. Since it attaches directly to the output of the RCP before any video processing is done, it requires fine pitch soldering skills to install.
I will not provide installation services. However, some people in the community may choose to purchase a lot of 20-30 units from me and sell N64s with the board already installed.
The board will work with both NTSC and PAL consoles.
Tentative release date is Q3 2014. To be honest it's one of many things I have going on, and I'd rather not release a crappy product, so it'll be done when it's done.
If you are interested in this product, consider putting in your information to the box below. It goes to a special mailing list created just for this. You will get one or two emails when something significant happens, and it's ready to go.
Like the 64drive, I don't have the funds to start a huge batch order out of pocket. So it will be a small pre-order, where the pre-orders help bootstrap production costs.
