    This actually takes the digital signal from the Dreamcast mainboard before it's turned into analog RGB.
    I really really really hope somebody will start selling pre-made QSB kit's for this :)

    Hey that's very nice! I've always wanted to play with FPGAs but I never had a proper feasible yet useful project!

    Now I only need to find the time...

    seems a product is near, to quote @citrus3000psi from reddit "Can't really give an ETA as I can't make promises. Hardware design should be finalized shortly. Waiting on new flex cables to arrive"

    New flex cables arrived today and they will be fine. I just ordered what should be the last PCB hardware revision. Firmware by chriz2600 is still being worked on heavily. I mean it works, but many features that we come to expect are still being added in. We don't want to release hardware too soon and have issues with future firmware updates, etc. Firmware will be easily update able via wifi.

    I will also be doing PCB fab assembly with this project. So there shouldn't be long wait times like gcdual preorder.

    Its going to be close to the other HDMI kits out there. This has a large custom flex cable, expensive FPGA and HDMI transmitter.

    fair enough, I'll probably buy it anyway because I super love the DC but just wondered what I was up against

    will be definitely worth the price if it displays proper resolution (unlike the bros devices) and 240p, 480i, 480p modes. day one buy for me for sure

    Yes it handles the proper resolutions and aspect ratios. It will also do integer scaling.

    240p > 480p/720p
    480i > 480p (BOB)
    480p > 960p and 960p (In 1080p frame)

    Those are great and sensible features.
    Are scanlines planned?

    Yep, even/odd/intensity will all be available options.

    Care to describe the "intensity" option?

    Could we get access to the code? I was always fascinated by FPGA but never had a project with one. This could be fascination to read/learn from.

    Its the thickness.

    All the code firmware code is on chriz2600 git https://github.com/chriz2600/DreamcastHDMI/
    He is handling the firmware, this project will be 100% open source, hardware and software. But like I said before I plan to do an assembly run for people who do not have the skills to build their own.
