- sxiin 5y agoAlso, check out Cathodemer. "Cathodemer is a realtime video production instrument with a CRT display simulator. It features analog-style RGB signal oscillation synthesis, input source mixing and manipulation, recursive color shape synthesis, sprite animation engine and various classic video effects." https://store.steampowered.com/app/697860/Cathodemer/ https://store.steampowered.com/app/697860/Cathodemer/
- wk_end 5y agoAlso possibly of interest is CLK aka Clock Signal, an emulator that outputs a composite "signal" instead of pixels: > Consider an ordinary, unmodified Commodore Vic-20. Its only video output is composite. Therefore the emulated machine's only video output is composite. In order to display the video output, your GPU must decode composite video. Therefore composite video artefacts are present and correct not because of a post hoc filter but because the real signal is really being processed. https://github.com/TomHarte/CLK https://github.com/TomHarte/CLK
- s1mon 5y agoThis is fun and all, but I'm not sure why one would go to the effort to simulate so much of the CRT experience, but not force the window to be the right aspect ratio?
- Cyberdog 5y agoI know, right? This looks even funkiner than probably intended on my vertically-mounted monitor.
- rzzzt 5y agoMaldita Castilla sports a very sharp, almost Trinitron-like appearance. The emulated display mask appears to have horizontal slits and is layed out like brickwork (see screenshots near the middle of the page, you'll have to zoom in a little): https://locomalito.com/maldita_castilla.php https://locomalito.com/maldita_castilla.php Does anyone know which type of CRTs had this look?
- 323 5y agoSomething is off, it didn't quite look like this.
- squarefoot 5y agoIt would need some blurring and low res pixelation to be convincing. Also, double images could be implemented to emulate signal reflections on obstacles.
- pedrogpimenta 5y agoMaybe it's the fact that it isn't really a tube screen, it's in fact a simulation of one through a modern screen. But thanks for such a constructive comment.
- BugsJustFindMe 5y agoThis is phenomenal. Absolutely beautiful. RIP my back button though.
- omginternets 5y agoIt's also a Web 1.0 simulator! ;)
- andrewstuart 5y agoYou can generate a real broadcast signal from a $5 esp8266 with this code: https://github.com/cnlohr/channel3 https://github.com/cnlohr/channel3 Here's the demo: https://www.youtube.com/watch?v=bcez5pcp55w https://www.youtube.com/watch?v=bcez5pcp55w
- kloch 5y agoNTSC has a number of artifacts but this simulation added RF decoding artifacts as well. The RF artifacts completely overwhelm the NTSC artifacts. It looks like a fairly weak RF signal plus other RF noise/harmonics in band.
- kmbfjr 5y agoI don’t think you can have colored snow in NTSC. But if you put the monitor next to a high magnetic field, then game on.
- mobilene 5y agoHunh, all the stations are UHF.
- omginternets 5y agoAnyone else attempt to tune into channel 99?
- a-dub 5y agothis is really impressive!
- dashwehacct 5y agoDarn. I switched to channels 3 and 4 and I still can’t play my NES. Did someone touch the VCR again!?!?
