You can change that by tweaking the GEOMETRY and BORDER params. Enter Quick Menu to change Shader Parameters.

Focusing on color balance, trying to not overdo anything. My monitor goes crazy on the bezel with that mask, hoping it is fine for you.
Raw parameters here, just load a koko-aio-preset and overwrite, need the latest koko-aio dev.

Sorry cyber, it was not a reply to your post, just hit the wrong button.

Am I alone in thinking this probably requires some black level adjustment? It seems like a lot of arcade games need it.

Definitely, even if the bactino screen was extreme, it is not getting that better in the game:
Supposing there were no gamma or saturation control back in the days for old crts, i just changed brightness and contrast:

On my old Commodore 1702 Monitor (which was basically a TV without a tuner and a second input with split Luma and Chroma at the back), there was also a “Colour” control, while on some other TVs there was a “Picture” control.

Mine in my scary and old cab seems to lack them. Just today I wanted to higher the saturation, because it seems it degraded or I never noticed, but my good ips laptop screen seems to have an higher Gamut (at least on the red, which is kinda orange-ish, on the crt, weird)

Nice stuff! These are looking really great!

Hello Hyllian. I was changing those parameters and got a good result. However, I notice that the 4 corners more than curving always have a small piece cut out with a curved shape…can this be avoided? I can’t see what parameter I can correct that with.
Sorry for muy Google-English, jeje

Trying to enter feature-freeze to finally release something stable, but still thinkering with bloom/ambilight parameters to craft somestable presets.
Youtube quality is really meh.

Cool implementation! Nice to see this project really take off.

Thanks, but I would swear those parameters are from the koko-aio shader, not from Hyllian’s royal shader
True.
As Hyllian said above, try the different border parameters… e.g. size and darkness. (Darkness at 0.06 will give a sharp edge and size will eliminate the round corner.)
Astal anyone?

Just took these off my OLED screen using my phone camera.
In person the colours glow naturally a lot more and they’re a bit more saturated.
Be sure to brighten your device when viewing in order to recreate the glow.
CyberLab Megatron 4K HDR Game SNES Composite
The shaders used are Sony Megatron Color Video Monitor and the updated NTSC portion of CRT-Guest-Advanced-NTSC.
It’s really difficult to capture the fullness and awesomeness of this shader combo. Give it a try yourself especially if you have an HDR display.

Great use of the overlapping mask, can I include that preset in koko-aio?
