Hi guys
I though I would let you know about the work i've been doing for the last few months. I have been developing a true 15khz output to a CRT giving exact resolution and refresh of the arcade or console.
I don't think many people are aware about it, I'm not into self promotion but I believe it is something lots of people including myself will be really interested in.
It currently runs on windows, Linux and Raspberry Pi, I will add though that Linux is the best OS to run it on. There are nearly no limitations on Linux. I have evolved this work into displaying native 240p on a 31khz display on all these platforms. I feel like this is something that I've not seen before so may be of interest to you guys.
Here is a video showing a compassion of the original hardware compared to the emulation. https://www.youtube.com/watch?v=BnT0EXkCeMc&t=2s
Check out my YouTube channel, it has all my previous work and is updated weekly. https://www.youtube.com/channel/UCT73WE ... subscriber
I hope you guys like it.
Emulation with true CRT output
Re: Emulation with true CRT output
Dude, this looks awesome
does this work with video cards that output vga? does the program cause any additional input lag that you know of? This could be really great for people who don t have the extron emotia.

Re: Emulation with true CRT output
That's a good question.
In Windows there is a noticeable lag. This is due the limitation of Windows refresh rates. Which mean the game refresh has to match a rounded number.
Linux on the other hand does not have this limitation. So I am able to set the refresh rates to 2 decimal places. This completely removes lag. It is down as low as 0.2 frames which is about 3 milliseconds. Its a good as playing the original console or arcade.
Yes this uses VGA out but will also work with HDMI, DVI and composite.

Re: Emulation with true CRT output
Isn't this exactly what CRT Emudriver/Switchres/GroovyMAME already does?
