Hmm. These have been around since v3.0, so it would count as a breaking change. And we'll still want to support them via hardware_compat.inc.

If we're adding and removing bootup register constants anyway, I'd like to take time and make sure we get it right+complete. Maybe someone more experienced than me with console detection can review Pan Docs and ensure our constants are good?

Also, can you please just have one "bootup register PR"? Don't worry about pushing more commits to it; after reviews/edits, if/when it's approved, we'll squash it into one commit with a sensible message (and update the hardware.inc version and history accordingly).

I guess this one is 6.0 then (applies to both comments).

Okay, please close your other PR and make all bootup-related changes in this one?

May I ask why? The other one isn't breaking.

Easier to deal with one changeset related to "bootup B registers".
