Will you be adding a DIP switch block, or is that too old-school?

As for the fourth configuration, the only other thing I can think that people might want to change is the switching behavior. For example, staying locked on the current input as long as it's active (which is the current behavior, yes?) versus automatically switching to an input when it becomes active, even if the current input is active; but who would really want that?
That would be hard because there is only one comparator / adc in the chain, which simply means that I can only check one input at a time.

Unrelated thought: If the gscartsw didn't have hardwired voltages for blanking and aspect, a switch array could be added to allow overrides for these, like forcing composite or RGB, forcing 4:3 or 16:9, or replicating/passing-through the source voltages.
So far nobody asked for such support. All RGBS input cases that I know of need 4:3 aspect, even WII. Also most users nowadays use either a PVM or XRGB / OSSC so these two SCART pins are ignored. Anyways SCART pin 8 and pin 16 are disconnected from inputs.
Actually I have a feature in mind which can be implemented, SMS doesn't generate fully compliant signal which confuses some PVM monitors, retrorgb asked whether this can be implemented and now I think it can be done as there are more logic cells on the new Altera IC.

Also, should theoretically be possible to power the gscartsw from a SCART source, but I imagine it would be too complex and expensive to add the components required to deal with power from multiple active sources and output 12V for the 4:3 override when only receiving 5V from a source (like an NTSC SNES), and I doubt anyone would have a real need for this.
Yeah, it was like this in the first switch version but so many cables were unreliable and I decided to power it up externally.
