My goal is to turn my TV ON and turn my console power ON and see an image.

Is that possible to display OSSC VGA, or Component by turning on the console's power switch?

This scenario would be great for people who want to play my collection without hunting down the video switch legend

Automatic input switching was requested in the OSSC Feature Requests subforum on VGP, although it is not a scheduled improvement.

There is a custom firmware with automatic input switching, but it's based on an older firmware.

In general, it would be simple to figure out which input (AV1, AV2, or AV3) has sync, and which format it is (RGBHV, RGBS, RGsB/YPbPr) based on which line has sync. The only part that might not work is detection between RGsB and YPbPr, as they have the same electrical specification (I've posited that it may be possible to determine between them by watching the voltages at rest, but no one seemed interested); so I believe that custom firmware was set up to default to YPbPr on AV2 and RGsB on the others, and there might be an override setting as well.

The alternative is to use additional hardware to convert signals to something like RGBS or YPbPr (depending on preference) and feed that into a single input on the OSSC.
