I’ve been using retroarch with the Genesis Plus GX core, and that seems to work well and is open source. Not everyone loves retroarch, but I’ve moved to it so I can use some of the more interesting HDR 4k CRT shaders

Was hoping to find this here, many happy childhood memories playing this one

Ok, then why does the same display work perfectly in windows? The display supports full RGB both 8 and 10 bit uncompressed. There is an open issue for this on the driver gitlab repo.

Don’t monitor shame me please. Also, the pixel density is within 5% of my 27" 1440p monitors.

One warning, if you use a display over HDMI, then you might have a bad time with Radeon on Linux. I use an LG C2 TV as my monitor, and there is a bug in the driver that forces it to a crappy ycbcr mode that ruins text clarity. I did try all manner of workarounds like hacking up the EDID profile, but I gave up and went back to Windows for now.

It’s a very specific issue, but a showstopper if it affects you
