New MiSTer hardware board

There are a few vendors out there that have taken a similar approach to HDMI, i.e. putting an HDMI-compatible socket on their product and never actually advertising it as "HDMI".

You can't purchase hdmi transmitter components unless you're a HDMI adopter (See https://www.analog.com/en/products/adv7535.html)

I agree with you on the DVI-I. As shown on the architecture bloc diagram I propose, I plan to implement DVI-I as a first step (https://www.patreon.com/posts/motherboard-v-47744392). It will output the same signal than HDMI but it will not embed the audio signal.

I guess that's a relatively new thing, because I'm sure I remember ADV7511/13 being normally stocked products at major distributors a few years ago. It looks like it might also be specific to Analog Devices products; NXP transmitters seem to still be available, and the datasheets only say that you need a license to use them "in equipment that complies with the HDMI standard". The main set of part numbers I see seems to be rated for only 150 MHz pixel clock rather than the 165 MHz rating of ADV7513 or TFP410, though.

Analog devices and Silicon image devices are locked if you're not an HDMI adopter. I did not plan to use the NxP parts as they seems to be tagged as obsolete (https://www.arrow.com/fr-fr/products/td ... conductors). You can still buy the NxP components but I don't know for how long.

I added the TFP410 part in my current design as its not an HDMI transmitter but a DVI one. So there is no restriction to use it for now.

I'd love to have a design based on an FPGA device that can be programmed using open source tools. Apparently there isn't much open source software in that category, though.

I don't think there is plenty of alternative to program the Cyclone V using open-source tools. It seems that if I replace the Cyclone V by Artix-7 fpga + external CPU, it would be possible to use the SymbiFlow open source toolchain. As the current PSX core development is based on Artix-7 fpga dev board, it seems that this target worth a look, but we are starting to move away seriously from the DE-10 Nano platform
