Do you know if there's an RGB modding resource for CRTs, similar in format to what you posted?
Cathode Ray Tubes
A place to discuss Cathode Ray Tube displays, especially with respect to retro (and modern) gaming. Upscalers, cabling, homebrew software, and related analog technology discussions are also encouraged!
Good question - CRT Database has some articles covering it. There's also this large shmups.org thread with a lot of detailed technical discussion, but would probably take a while to parse.
Retro Tech on YouTube also has several videos covering RGB mods too, if I recall correctly.
This looks promising:
https://consolemods.org/wiki/CRT:RGB_Video_Modifications
It appears to be a sub-section of the CRT Wiki in your post.
These are excellent options. I’ve used that shmups thread a ton, but you’re right. It’s super hard to parse. I really wish it was broken out or consolidated into a more usable format.
