    Here is a video of the working prototype.

    I thought there would be a bit more excitement over this since the video will be better than nesrgb. Also the video will be more standard so it can be used with any hdmi tv(no more having to mess around with rgb).

    I think most people here are too young for nes now.

    I want to know what upscaling method they use

    Not sure if it's just horizontal or vertical too, but it looks like linear/bilinear interpolation. Only a few lines are buffered in internal block RAM so it can't be much more complicated than that.

    Something not really explained is that *all* audio is emulated rather than digitized (not just the "expansion audio"), so in effect it is a partial clone.

    1080p really isn't much of a selling point since 720p scales better for 240p (and upcoming 4k & beyond TVs can losslessly scale 720p). It also doubles the bandwidth over 720p, which either increases the hardware cost, or lowers reliability.

    Too bad it's not for Famicom. That'd be the only thing I'd be interested in.

    Hopefully I'll be able to install it in my famicom!

    I am highly interested in this, but don't have an NES. Waiting for this to be available first before I think about getting a NES.

    Waiting for this as well , gonna grab a kit when they become available.
    Pretty sure the famicom will work just fine.

    So use an AV Famicom or a Twin.

    Might just hold onto these for a while longer: :p

    I'm really intrigued by this. It sounds like Kevtris is throwing in every single option he can possibly think of. Probably going to cost double the price of an NESRGB, but may be worth it. Wonder if Buffalowing will come up with an HDMI back panel for the AV Fami/NES-101, as their installation process appears to be to drill a hole on the side of the console at the moment, which I wouldn't personally want.

    I've already start looking into it since last night. I have drafted some preliminary designs on CAD. A custom pcb will need to be design in order to achieve a clean look and install. The easy way would be just providing a blank 3D panel with a cut out to accommodate off-the-shelf panel mount HDMI socket. But the back of the AV Famicom/Toploader is quite shallow, most ready made panel mount HDMI pigtails will likely have the cable sticking toward the cartridge slot which will interfere with putting back the top plastic casing back on. Besides, I don't think anyone want to see screw head(s) exposed on the panel either. Anyway, I won't have anything more concrete until they finalize their design and have their kits for sale. I'm developing this independently from them so any solution I can come up with will greatly depend on how they roll out the final product.

    Yeah, I was looking into yesterday and thought a custom PCB would be needed - still, by the sound of it, I reckon it'll be 6 months or so before the kits are for sale, so plenty of time.
