TheRetroChannel has just posted a video demoing the original OSSC’s new lumacode support – A way to route a digital video signal from certain classic consoles over one wire, allowing the OSSC to do a clean digital upscale and mix in analog audio. This code was created by c0pperdragon and works well with 8-bit computers and consoles like the Atari 2600, Commodore 64 and Colecovision. When used with the OSSC, you’ll simply need to create a custom profile for the console and load it to switch to the console/mode. This results in a low-lag output that was measured at definitely less than one frame. More info after the links:

I think this is a really exciting development for 8-bit machines and I can’t wait to see more about it! Once the NES core is a bit more complete, I’d like to run some more in-depth lag tests to try and verify the exact number added, however even with these preliminary tests, it looks like you won’t have to worry about it at all. That means a handful of older consoles and computers can now have a much easier and potentially higher quality way to pull RGB and HDMI signals.
I’d also like to see more info on the RGB output c0pperdragon’s external kits can provide! While most people might be thinking of the exact use case TheRetroChannel demo’s above, there’s definitely a bunch of us CRT enthusiasts that I’m sure want to try this as an RGB mod! We’ll be covering Lumacode a lot more on RetroRGB, but please consider subscribing to TheRetroChannel for their videos on it as well.
Speaking of that, TheRetroChannel also recently demo’d c0pperdragon’s lumacode alpha support of the NES. While it’s not quite ready for an in-depth comparison, this has the potential to add a #nocutmod to the original NES and Famicom and it doesn’t require removing the PPU at all!
