Hardware register default value doesn't make sense on DMG for CGB-only registers about pandocs

No, they read as $FF and writes are ignored. I believe the current values were taken directly from the source code of a test ROM which runs in DMG mode, which was a bit of an oversight.

Sure, -- should work too. (Perhaps three, so they stand out even if not in a <code> block.)

I feel like I should bring this up since it's somewhat related, but the CGB-only registers in the CGB / AGB column are also misleading/technically correct, for DMG mode only (which isn't mentioned anywhere). Some registers are marked as ?? with a footnote for compatibility mode, but others are marked as $FF with no indication that it's not the actual value. I think it would be more useful to list the actual values of all these registers on CGB / AGB, and describe the $FF behavior in compatibility mode under the footnote for this issue.

I believe the GBC-only regs are still R/W in DMG mode, just inoperative? I'm not certain, though.
